3. I’m a supporter of TNVR.
let me say that it is appreciated. an undertaking of the magnitude of of tnr needs all the help it can get.
while i am glad you do support TNR you seem to have fallen prey to the inaccurate info and blatant lies that are presented by zealots from the opposition.
there is no way to TNVR every adult cat in one neighborhood,
of course there is, i did just that in my neighborhood. sure, it took me about two years in total but that was mainly due to the fact that i was doing it by myself. i am certain that if i had more resources/manpower it would have been done in less than a year.
The impact on their environment is decided on how often they are fed, how much they are fed, and the quality of the caretaker’s programs. People should be well aware that a fed cat will still hunt down and kill something that catches his fancy. A cat that is no longer fed will hunt down and kill twice that number of prey.
feral cats are opportunistic feeders—they will eat whatever food is easiest to find that will also satisfy their nutritional needs. today, feral cats’ main source of food is almost always people’s garbage. feral cats today scavenge on the scraps that all human habitats inevitably produce.*

a study of a feral cat colony in Brooklyn found that the cats depended more on local garbage for food than on either prey or feeding by caregivers, and that the neighborhood produced enough garbage to feed three times more cats than actually lived in that area*

Compare feral cats and TNVR to an oil spill.
that's some pretty big league hyperbole right there.
Feral cats and Oil spills are both caused by humans; both are a type of pollution that is harming the wildlife.
yes, by helping to control the vermin population.
we could be like Macquarie Island, where, in 2000—after 15 years—cats were finally eradicated. forty-plus years of rabbit control was “reversed in only six years,” devastating the island’s vegetation. in addition, “a pulse of at least 103,000 mice and 36,600 rats have also entered the ecosystem since cat eradication.” *

for more than 10,000 years, cats have lived outdoor lives, sharing the environment with birds and wildlife.
decades of studies prove that when cats do hunt—which is not nearly as often as they scavenge—they much prefer a diet of rodents. studies have shown cats to be far more efficient hunters when they sit and wait for prey—outside a rodent burrow, for example—than when they stalk and pounce, the way they approach birds*

But it can only be done with available veterinary low-cost service and volunteers willing to do it. And the cats can still cause a reduction in wildlife.
cat predation is often “compensatory predation”, preying on animals that would likely have died anyway from disease or hunger.
studies show that the animals caught by predators are generally weaker and more diseased than those killed by manmade source *1, *2

Oil spills and feral cats are a type of pollution. The feral cats pollution is not as quick acting as oil spills are, but is just as damaging to the environment of 10 years ago.
again with the hyperbole. see above
This image of a feral-cat-free environment is something that could have been 50 years ago.
domestication/socialization of cats is a recent (in the big picture) event. again, for more than 10,000 years cats have lived outdoor lives, sharing the environment with birds and wildlife. so i question why would you hope for such a goal?
The reality of it is, we can TNVR or we can let the cats kill more wildlife than already done (squirrels, birds, rabbits, rats),
seeing as how hyperbole such as this have already been disproven [see above] i will add only one thing; millions of bird deaths occur every year due to human activities—nearly 100 million from colliding with windows, 80 million from collisions with automobiles, and about 70 million from exposure to pesticides.*1 Our own government tracks how many animals (birds included) it kills—over 4 million in 2009 alone.*2

by this logic i suppose we should aim for extinction of lions, right? after all, think of how many elands are killed by lions each day.
scavenge dumpsters, breed, and spread disease.
scavenge dumpsters? sure. not sure how that is a big problem but if so is it just as big of a problem when a dumpster is "scavenged" by a racoon? or a possum? or a bear? what about when it is by a homeless person?
breed - yes, but the numbers that the "kill em all" bird zealots purport are totally incorrect. a study of “71 sexually intact female cats in nine managed feral cat colonies” found that: “Cats produced a mean of 1.4 litters/y, with a median of 3 kittens/litter (range, 1 to 6). Overall, 127 of 169 (75%) kittens died or disappeared before 6 months of age. Trauma was the most common cause of death.” *

This program is worth it, it is not a solution, but it is something to slow the process of the destruction of what remains of our environment until a long-term solution is found.
i agree that we need to address the destruction of the environment, however we should TNR the real cause - humans.

TNVR can be considered a 'Slow Kill' it's a dream of extinction that is moving slower than the growth rate but slows it just enough to be worth it.
"dream of extinction"? i really am at a loss for words.

quote mining? you interwove quotes from the esteemed attorney Degani with false propaganda proported by zealots from bird groups.
My response post, the original post I responded to spoke of concerns of diseased cats running rampant due to a lack of vaccinations:
as cited above, there is no science to back up your claim. however i will add that according to the Centers for Disease Control and Prevention statistics show that bats are now the number one source of human rabies exposure in the U.S., and that raccoons and skunks are the most commonly infected species, followed by bats and foxes. today more than 90% of rabies cases occur in wildlife—92% of cases in 2009 and 2010.
"Skunks and raccoons are major sources of rabies, and most cats who are faced with a challenge by a skunk or raccoon will run away, whereas a dog is more likely to attack. When faced with non-prey animals, cats are generally defensive animals rather than offensive animals, and the small rodents such as squirrels, chipmunks, rats, mice, and rabbits that feral cats may hunt are rarely infected with rabies."*

I did it because people were keeping food out and if I trap/killed then another cat would just take their place.
killing a cat is a criminal offense in all 50 states and the District of Columbia, regardless of ownership. anti-cruelty laws apply to all cats—companion, abandoned, lost, and feral.
"Well-intentioned people argue that it is our humane responsibility to kill ferals kindly, rather than let them face the rigors and perils of an uncertain future. When I observe a recently caught feral cat, cringing in terror in the corner of its cage, I see a being not altogether unlike myself. If I were that feral facing immediate, albeit painless death, or a chance at life replete with all the perilous uncertainties it holds, I would choose life. And so for these ferals, I can choose no less." - Cole Mcfarland
Feral cats are living longer, I've had the smart ones live as long as 8 years...<snip> Most feral cats don't live past two years.
many can and do live much longer. my most recent one is about 10 and one of my original members is about 9. not to mention Snowball (a.k.a. Grandmom), one of the boardwalk cats that lived to 20.
A 2012 nationwide survey conducted by Alley Cat Rescue revealed similar longevity: one quarter of TNR organizations responding to the survey have colony cats in the 6–8 year range; 35 percent in the 9–12 year range, and 14 percent reported car*ing for cats 13 years of age or older.*
*Alley Cat Rescue (2012). Alley Cat Rescue’s National Feral Cat Survey.
catch and kill, other than being inhumane, is (fortunately) frowned on by the public. over 80% of americans believe that leaving a stray cat outside to live out his life is more humane than having the cat caught and killed.*

One way to know if someone is doing TNVR for feel-good reasons is how they see the cats. In the past years I've learned (for lack of terminology) intermediate rankings in the biological classifications of felines from fellow TNVR volunteers that I find helpful in recognizing the difference of these animals
Feral: An animal in a wild state after escaping captivity or domestication, these animals are usually several generations removed from domestication, but not enough generations removed to be considered wild due to their reliance on human intervention (whether medical or resources) to survive.
Stray: An animal that is no longer a part of the domestic environment that it relies on for survival.
Wild: Living or growing as a part of the natural environment, these animals and plants have never been domesticated or are so many generations removed from domestication that they no longer rely on human involvment to survive.
Tame: An animal that is wild by several generations and has been brought into a domestic setting or is tolerant of human interaction but does not need human involvment to survive. These animals are usually used in circus and zoo settings, wolf hybrids of the first few generations, and exotic kept pets that; in their natural environments would thrive and survive without human intervention.
Domestic: An animal that depends on human intervention for survival and seeks human attention. These animals are usually companion animals and have been many generations dependent on human intervention in medicine and resources to thrive.
Companion: An animal that is domestic and kept for the pleasure of the company of the animal. These animals are often used as service animals and therapy animals due to the emotional connection and friendships formed between the species.
sort of splitting hairs there. there are socialized and feral. tame and domestic - one and the same, socialized. a stray is just a lost/abandonded socialized cat. wild and feral - one and the same, feral. the longer a cat has been feral the longer it takes for them to learn to trust and therefore become socialized.
Feral cats can not be companion animals because they do not want human interaction. They can not be domestic because they do not depend on humans for medical intervention or seek human attention. They can not be tame because they were never wild in the first place. They can not be wild because they are the creation of many generations of human intervention that has been unnaturally released into the environment. They can not be stray because they are too many generations removed from domestic life.
well, as a guy that has socialized a few feral cats i can say that nothing is further from the truth.
If someone sees Feral cats as anything other than feral, they are most likely doing TNVR for the feel-good properties
i would venture a guess that anyone that does volunteer work does get a good feeling from doing it.
not for the progress of elimination of the feral intermediate ranking of the feline species. This process of extinction is not fast
thank god that people with that attitude are in the vast minority.
if their population was not controlled and if FeLV FIV positive cats were not trapped and euthanized.
well, the two FIV+ ferals that i have trapped sure are glad that you are not anywhere near them. funny that none of my other ferals are positive.
as a result, preventing the mass-spread of disease.
again, see above.
They can't miss what they've never had, and usually they despise what they've never had when you try to domesticate them.
based on the ones that i have socialized nothing could be further from the truth.
which I personally think feral cats should be a subspecies of the domestic cat
so are criminals a subspecies of the human race? "feral" cats predate "domesticated" cats, so isn't it the other way around?
