Default too young to spay/neuter?

We were supposed to take Kayla and Sadie in to get spayed on the 16th. But Sadie has gone missing (feral). So my mom wants to take one of the kittens to get neutered instead. They are 10 weeks old. I think if we were going to get any of them "fixed" it should be one of the females so when they do go to their new homes we won't have to worry about them having babies. But we are having a hard time finding them new homes and she said she doesn't want the males to start spraying . Anyways, is 10 weeks too young?

Males usually won't start spraying until they are around 7 months old. I have never seen neutering done as young as 10 weeks, and we only neuter after 4 months of age. I know they do neutering younger in the US, though. I hope you find your lost baby.

Thank you for replying so fast . I tried to tell her that they don't spray so young but she wouldn't listen. I really don't want to have to put them through it so young. Hopefully the vet will tell her to wait. It would be great to have some of them "fixed" before they go to their new homes though. I hope Sadie comes home soon. I am really worried about her. Her mom was missing for a week and she came home, so hopefully Sadie will come home soon too. It isn't like her to wander off like this. She usually stays in the yard.

Birdgirl, please give your mom the following information to get her to listen:

Potential Reasons for a Cat to spray:

sexual maturity

temperament of the cat

the appearance of a strange cat in the yard

the addition of a new pet or family member into household

scent of unfamiliar cat on owner's clothing or shoes

tension or aggression between companion pets

number of cats in the home

renovation or remodeling

move to a new home

unfamiliar visitors

change in owner's schedule


The age at which a male cat reaches sexual maturity and begins to produce sperm varies from 6 to 18 months, the average being about 9 months. Two months later, sperm is present in the collecting tubules, so the male has reached sexual maturity and can now fertilize a queen.

There is no reason, none, for fixing a ten week old kitten. It's way too soon and it doesn't make any sense. No sense whatsoever.

Thank you so much. I will show her. I'm 19 and she acts like I'm a little kid. Just will not listen to what I have to say. We have 4 male kittens and she is being paranoid. She thinks that if we still have them in a couple weeks they will start to spray . She is the one that let Kayla out every single day without being spayed in the first place and now she refuses to help me find them new homes. She says that if I don't find them new homes in a few weeks she is taking them to the shelter . She loves animals and she has never acted like this before. I don't know what her problem is.

The standard for Ragdoll breeders in Texas has become 12-14 weeks, assuming the kitten has reached normal size for its age. Early spaying/neutering has become the norm rather than the exception for these breeders. Minimum weight used by most is at least 3 pounds, which most Ragdolls will have achieved by 12 weeks.

All pet quality kittens are taken to a clinic that specializes in spaying and neutering. This clinic routinely does spay/neuters on kittens that are at least 3 months old and a minimum of 3#.

What does this mean for you? Well, basically it means that your kitten will be neutered between the ages of 12 to 16 weeks of age. They are typically neutered on Saturday and when the vet feels that the kitten meets her requirements for surgery. Weekend surgeries allow us to more closely monitor the kittens progress.

Your kitten comes neutered. You don't have to go through the intensive post operative care and attention that a kitten needs after surgery. As breeders we believe we are better able to provide that care for your pet.

Kittens can leave 7 days after surgery. It is extremely important to keep your kitten from jumping around and doing things that they shouldn't do. We do not want them to tear any internal sutures or remove the surgical glue used to seal their incision.

The concept of early spaying and neutering is not a new one. The it has been practiced for over 50 years in North America. It was not until much later that questions and concerns were raised about the possibility of negative side effects in practicing this procedure.
Concerns that were raised, while determining at what age an animal should be spayed or neutered, were that the animal may suffer from long term effects such as; stunted growth, a higher tendency to obesity, a lack of desire to be active or an undesirable behavior pattern. It was believed waiting until a patient was older increased the safety of surgery, as well, concerns that early altering could increase the incidence of feline lower urinary tract disease, have been voiced.

These concerns have been tested and researched thoroughly by many different universities and have resulted in some findings that are worth studying and understanding before making any conclusions on when to spay or neuter your pet. Studies Conducted on the Benefits or Drawbacks of Early Spay or Neuter done by The University of Florida, were funded by The Winn Feline Foundation in conjunction with the American Veterinary Medical Association (AVMA). These studies were conducted on animals ranging from 7 weeks old to 12 months old. The extensive studies were monitored very seriously and concluded that the spaying or neutering of an animal, before it has reached sexual maturity, has no known ill side effects. On the contrary, research has founded that early spaying or neutering of your pet can aid in the recovery process, giving your pet a speedy and virtually painless recovery. Years ago, when safe pediatric anesthetic techniques were not available, waiting until a patient was older increased the safety of surgery. Altering no longer needs to be delayed for this reason.

Results from the studies performed in Florida were as follows: Growth may be prolonged if the procedure is performed prior to sexual maturity or the animal's first heat. However, this can be a benefit for the pet owner who has an unusually small pet and would like for it to become a little larger.

Observations of urinary tract development showed no differences between those altered early and those altered post 7mos other than the differences related to sex. The investigators measured the diameter of the urethra in the male kittens and found no differences between the groups. Contrary to popular belief, the neutered group of animals were just as active as their unaltered counterparts. Spaying a female can actually protect her against mammary cancer and uterine infections. In males, neutering reduces the risk of testicular cancer and enlargement of the prostate and related infections. From a pet owners point of view, the altered pet is a much better companion than their unaltered counterparts. They have a tendency to be less aggressive and more affectionate, and since they are not motivated by the urge to reproduce, they are less prone to roam and fight.

Why Advocate Early Spay & Neuter?
There are obvious reasons to spay or neuter your pet as soon as possible. These reasons are for the general animal population or for your pet's health in general. Population Control is a growing concern and by spaying or neutering your pet, you can help contribute to reducing this problem. Responsible pet owners can and should make a collective effort to insure that all pets are neutered preventing any further increases in unwanted pets. Susan Dixon, DVM fully endorses early altering and has done hundreds of baby kittens. "The surgery is EASY and the kittens heal so fast".

A Healthy Pet is a happy pet and the earlier they are spayed or neutered the less likely they are to remember the procedure and the more likely they are to have a speedy recovery

Early Spay/Neuter in the Cat
by Susan Little DVM
While it may seem that interest in early spay/neuter is a recent phenomenon, it has not only been talked about, but it has been practiced for over 25 years in North America. Early age altering refers to spays and neuters done between the age of 6 and 14 weeks. Altering pets between 5 and 7 months of age was established by tradition rather than for any specific medical reason. Years ago, when safe pediatric anesthetic techniques were not available, waiting until a patient was older increased the safety of surgery. But we no longer need to delay altering for this reason.

People working to decrease the problem of surplus dogs and cats in the United States pioneered the idea of early altering. While surgical sterilization remains the most effective means of population control, delaying the surgery long enough for sexual maturity to occur defeats the purpose. Animal shelters advocate mandatory altering, but many adopted animals either are never altered or have at least one litter first.

Over the years, the safety of early altering has been questioned, mainly by veterinarians who may be unfamiliar with the surgical and anesthetic techniques required for pediatric patients. As well, concerns that early altering could increase the incidence of feline lower urinary tract disease, could affect skeletal development, and affect behavior have been voiced. These concerns have largely been laid to rest by many studies, and early altering is becoming more widespread and available. A study recently published by researchers at the University of Florida found no significant differences in the physical and behavioral characteristics of cats altered at 7 weeks of age compared to those altered at 7 months of age.

Very important work has been done by Drs. Michael Aronsohn and Alicia Faggella at the Massachusetts SPCA on the anesthetic and surgical techniques for early altering of dogs and cats. In 1993, two papers were published outlining their work on the early altering of hundreds of kittens between the age of 6 and 14 weeks. They evaluated several anesthetic protocols and made recommendations for safe handling and anesthesia in patients of this age. Some small changes to surgical technique are necessary for patients in this age group. As well, these young patients must be handled a bit differently both before, during, and after surgery. The changes in surgical protocol are simple and easy to carry out, and the experience of these veterinarians with early altering is overwhelmingly positive.

As cat breeders, we must do our part to curtail the serious issue of surplus animals. Many of us work in breed rescue programs and give our time and expertise to shelters. We can ensure that our own kittens not destined for breeding programs will never reproduce by practicing early altering. Early altering is a safe and effective means of ensuring we do not unwittingly add to the burden of unwanted pets.

A Winn Feline Foundation Report On ...

EARLY SPAY/NEUTER IN THE CAT
Are fears of negative side effects of early neutering warranted? Background and medical issues including a summary of an ongoing Winn Foundation funded project to evaluate the long term effects of early altering.

Developmental and Behavioral Effects of Prepubertal Gonadectomy. Mark S. Bloomberg, DVM, MS; W.P. Stubbs, DVM; D.F. Senior, BVSc; Thomas J. Lane, BS, DVM; University of Florida at Gainesville. Funded by the Winn Feline Foundation, February 1991. Continuation funded February 1992.

A progress report on a study funded by The Winn Feline Foundation

Summary prepared by Diana Cruden, Ph.D.


--------------------------------------------------------------------------------
The concept of early spaying and neutering (e.g. before the animal is sexually mature) is not a new one. In the early 1900's, early neutering was the norm and it was not until much later that questions were raised about the negative side effects of such a procedure. Today most of the experts acknowledge that there has not been enough scientific information available about the most appropriate age to neuter a pet. Until recently, there was no research data that either supported or disproved the idea that neutering dogs and cats at ages younger than five to eight months was deleterious. There is, in fact, little scientific basis for selecting this age group as the most appropriate time for neutering. Indeed, one investigator points out that many veterinarians have been practicing early neutering for years, since there is an incredible range of ages when puppies and kittens reach sexual maturity. Large animal practitioners have long practiced early neutering on their livestock and consider it not only acceptable, but desirable in many cases. Even before concerns for the burgeoning population of unwanted pets raised our collective consciousness, there were many scientifically documented reasons to spay and castrate. Spayed females are protected against mammary cancer and uterine infections. In males, castration reduces the risk of testicular cancer and enlargement of the prostate and related infections. From the pet owners point of view, the spayed or castrated pet is a much better companion. They are less aggressive and more affectionate than their unaltered counterparts. Since they are not driven by the urge to reproduce, they are less likely to roam and fight.
Controlled studies into the short- and long-term effects of early neutering have been sadly lacking until recently. While there had been numerous anecdotal reports of early spaying and neutering, these cases were generally uncontrolled from the scientific viewpoint. Most reported cases were random bred, unrelated animals from a variety of backgrounds and no attempt was made to control for these variations. There have been few university based studies in this area. M.A. Herron of Texas A&M reported in 1972 that neutering before sexual maturity had relatively little effect on the diameter of the urethra in male cats. Studies have more recently been conducted at Angell Memorial Hospital in Boston, the College of Veterinary Medicine at the University of Minnesota, and the Department of Small Animal Clinical Sciences at the University of Florida. The Florida project, begun in 1991 and completed in 1992, was funded by the Winn Feline Foundation in conjunction with the American Veterinary Medical Association (AVMA). A serious attempt was made in this study to limit background influences and genetic variation. The kittens were bred especially for the project and litter mates were divided among the three groups. The queens were bred and housed in quarantined facilities since both pre- and post-natal nutrition and other factors can contribute to the ultimate size, weight, and overall health of the kittens. Dr. Mark Bloomberg indicates that although long-term follow-up results are incomplete, the initial results are extremely positive. Prior to undertaking the Winn Foundation study, Dr. Bloomberg had completed a similar study in dogs. Animals involved in that study have now been followed for over five years, with no negative side effects reported. In the Winn Foundation study, there were a total of 31 domestic shorthair kittens from 7 litters born on the Gainesville campus.

The kittens were divided into three groups:


Group 1 (11 kittens) were neutered or spayed at 7 weeks of age.
Group 2 (11 kittens) were neutered or spayed at 7 months.
Group 3 (the control group of 9 kittens) were not neutered until maturity and after the completion of the first phase of the study at 12 months.
The investigators reported that the surgical procedures in the Group 1 kittens were straightforward and uncomplicated, and that the kittens recovered even more rapidly than the Group 2 kittens and Group 3 cats. Dr. Bloomberg notes that although there is very little material on pediatric anesthesia in animals, the pediatric patient in human medicine is generally considered to be a very good surgical candidate and there is no reason why this should not also be true for dogs and cats. The major concerns in pediatric surgery are: preventing hypothermia (maintaining body heat); utilizing proper doses of anesthetic agents (since the respiratory centers are not as well developed in the pediatric patient); and maintaining proper blood glucose. The investigators did not fast the pediatric patients as long as adult patients and administered small amounts of Karo syrup prior to induction of anesthesia as a precaution. It should be noted that due to the rapid recovery of the pediatric patient, the common practice of reducing anesthesia during final stages of the surgery was modified.

Critics have claimed several possible detrimental side effects from early neutering. It is commonly believed that neutered animals are less active and more prone to obesity than unaltered animals. It was also suggested that neutering at an early age would stunt normal growth. In male cats in particular, it was feared that early castration would affect the development of the urinary tract and lead to an increased incidence of cystitis or urinary obstruction. Concerns have also been raised as to the effect of early neutering on behavior, food consumption and dietary requirements, etc. The investigators attempted to answer most of these questions by evaluating several parameters in the three groups of kittens. In particular, they looked at weight and body composition (i.e., percent of body fat); bone length and the age of physeal closure (the age when long bone growth stops); behavior; food consumption; development of the urinary tract; and the development of secondary sexual characteristics and degree of sexual maturity.

The results of the comparisons of weight showed some differences between the three groups. Males weighed consistently more than females, but this was uniform in all groups. The studies of body composition and body fat indicated that Group 1 (neutered at 7 weeks) and Group 2 (neutered at 7 months) were identical and were generally fatter than Group 3 (neutered at 12 months, after they were sexually mature). Investigators point out that by 12 months, the male cats in Group 3 were already exhibiting the normal adult male characteristics of decreased weight and the development of jowls, which accounts for some of the differences. It has also been noted that in the course of follow-up, the differences between the weight in cats from Group 1 and 2 and Group 3 are becoming less apparent. All these cats have been placed in selected and supervised pet homes and are more active than they were in the University facilities. A three-year follow-up exam was to be conducted in May of 1994.

OBSERVATIONS
There was generally no difference in food consumption between the three groups other than the differences between males and females, which were consistent in all groups. There was no difference observed in the growth rates in all three groups, although the males grew faster in all groups. Increased long bone length was observed in both males and females in Groups 1 and 2. This appeared to be due to the fact that physeal closing (closure of the bone growth plate) was delayed in Groups 1 & 2. This explains why cats neutered and spayed as kittens are frequently larger (longer and taller) than unaltered cats or cats altered later in life. This seems to be particularly true for males.

In terms of behavior, after 7 months, the cats in Group 3 were noticeably less affectionate and more aggressive prior to altering than the cats in Groups 1 and 2. Contrary to popular opinion, neutered animals were as active as their unaltered age mates.

Observations of urinary tract development showed no differences between the three groups other than the differences related to sex and these were consistent across all groups. The investigators measured the diameter of the urethra in the male kittens only and found no differences between the groups. Concerns have been raised that early neutering would result in smaller diameters in the urinary tract, resulting in an increased incidence of cystitis and related problems. This does not appear to be the case. The main differences observed between the groups occurred in the comparison of secondary sex characteristics. Males were examined for differences in the development of the penis and prepuce (skin covering the penis), as well as for the development of penile spines. The penile spines were absent in Group 1, smaller than normal in Group 2, and normally developed in Group 3. In the examination of the female kittens, investigators found that the vulvas were more infantile in Groups 1 and 2 and normal in Group 3. None of these differences had any impact on the ability to catheterize the kittens. Concerns that development of the urinary tract might be arrested or impaired by early spaying and neutering proved unsupported.

The results of this study so far indicate that the differences between cats neutered at 7 weeks and 7 months are insignificant. The differences observed between animals in Groups 1 and 2 and the animals in Group 3, while in some cases statistically significant, are not differences which appear to affect the health of the animal in a negative way. While the final results will depend on the analysis of long-term follow-up, the indications are that early neutering is not detrimental to the overall health of the animal. From the perspective of shelters and particularly in respect to the problem of surplus puppies and kittens these results are encouraging. If all the animals adopted from shelters, including puppies and kittens, are neutered prior to adoption, there should be a corresponding decrease in the numbers of animals euthanized each year in this country. Preliminary results from Alachua County, near the University of Florida at Gainesville, would seem to support this theory.

Alachua County Animal Control has been working with the investigators at the University and have had an early neuter policy in place since 1990. No animal leaves the shelter without being neutered. In 1987 the county euthanized 1,250 cats and dogs per month. Since implementing the early neuter policies they have seen the numbers drop to 940 per month in 1992 and there has been no increase in morbidity or mortality associated with the program.

In the last year, recognition of the safety and efficacy of early spay/neuter has grown rapidly. The American Humane Association has endorsed early neutering prior to adoption as a "feasible solution to decreasing pet overpopulation and the tragedy of resulting deaths." In July 1993, delegates to the American Veterinary Medical Association Annual Meeting voted to give AVMA's support to the concept of early neutering. Work done by veterinarians at Angell Memorial Hospital for the Massachusetts Society for the Prevention of Cruelty to Animals supports Dr. Bloomberg's observations. Other organizations involved in early neuter programs include the Denver Dumb Friends League in Colorado, the Miami Humane Society and Alachua County Animal Control in Florida, The Humane Society of Austin and Travis County in Texas, the Chicago Animal Control in Illinois, the King County Animal Control in Washington state, the Vancouver SPCA in British Columbia and the Southern Oregon Humane Society in Oregon. The Dekalb Humane Society in Decatur, Collie Rescue of Metro Atlanta, the Georgia Alliance of Purebred Canine Rescuers, The Haven (dog rescue) and Dog River Sanctuary in Douglasville are among the Georgia organizations working with early neuter in dogs and cats, as well as exotic species.

The Cat Fanciers' Association (CFA) has changed its show rules to permit altered kittens to compete. Many breeders of pedigreed cats are working with their veterinarians to neuter pet quality kittens prior to placement in new homes. Those breeders who have adopted this policy report that they are very happy with the practice. New pet owners indicate that acquiring an already neutered animal relieves them of the worry and expense of scheduling the surgery at a later date, enabling them to relax and enjoy their new companion. As is the case for shelter managers, breeders can relax in the knowledge that the kitten they place today is not going to contribute to the surplus pet population tomorrow.

I live in Los Angeles and recently got a new kitten from the pound. He was just 6 weeks but they would not release him until he was neutered. Iwas very surprised that they neutered so young but that's their new policy. I talked to my vet about it and he said a lot of places are doing it and they have found that there no health problems associated with doing it so young. I'm still skeptical but, since I wanted to get a cat from the pound I didn't have a choice. Hope that helps.

All very nice, but the facts still are that

1. a 10 week old kitten is far too young to be spayed/neutered

2. 10 week old kittens do not contribute to pet over-population.

There are other opinions regarding early spay/neuter but usually those opinions are ignored and nowhere is objective, detailed discussion encouraged. Like so many other things today, early spay/neuter is aggressively advocated. Those who advocate it, however, conveniently ignore other, even more important issues involved in pet over-population.

I think it depends on the individual circumstances.

If you're in a shelter environment, you either spay/neuter at 10-12 weeks, or you end up with a shelter full of 6 month old kittens that no one wants because they're "too old." Given the percentage of adopters whose checks bounce, I don't hold up a lot of hope for spay/neuter contracts being observed on a large scale (nor do I expect to see big grants rolling in to pay for enforcement of them, either). Unaltered 10-week old kittens don't contribute to pet overpopulation, but the people who adopt them sure do.

Now, if we're talking about MY personal kitten (not that I would have a kitten, because I'm not fond of them, but hypothetically speaking), I would likely wait rather longer to neuter unless I was trying to rehome him, simply because I know that I would be on top of the situation (not to mention that my vet would be ringing my phone off the hook to make sure he got in for the surgery). If I was trying to rehome in an urgent situation, and didn't know each adopter very well, I'd alter as soon as my vet was comfortable with doing the procedure, just so that I would KNOW it was done.

So it just depends on individual circumstance.

I am not going to have my cat spayed until she is almost four months, but @ the shelter I volunteer @ they are done @ 8 weeks and there has never been a problem.
