Well when you put it that way, I guess that makes a lot of sense.
Iíve been thinking about what scottd said and to tell you the truth, I donít know why we are doing this. And except for the rabies, I really donít know what the other stuff is exactly.
The other killed vaccine (besides rabies) is for feline leukemia. It's a virus that can be lethal. It's transmitted by close contact. You said your cats are indoors and I assume they're all negative. In my opinion, this is vaccine is entirely unnecessary. I would only consider it if my cats went outside, were around unknown status cats, or if I had a positive cat living with negative cats.
The FVRCP vaccine is a combo vaccine that protects against 3 different viruses:
Feline viral rhinotracheitis (FVR) is an upper respiratory infection of cats, also known as feline influenza, caused by feline herpesvirus 1 (FHV-1). FVR is very contagious and can cause severe disease, including death from pneumonia in young kittens.
Feline calicivirus (FCV), in addition to FHV-1, is the other common viral cause of respiratory infection in cats.
Feline panleukopenia virus (FPV), more commonly known as feline distemper, is caused by the feline parvovirus, a close relative of canine parvovirus. It is not related to canine distemper. Panleukopenia is highly contagious and can be fatal.
The FVRCP vaccine is important to establish immunity but it's not necessary every year. I give 2 doses at 8 and 12 weeks and then a dose at 1 year. The AVMA recommends a booster every 3 years after that. I personally do opt for a booster because I have foster kittens regularly and the transmission is easier for these viruses. If they stay indoors and aren't around other cats, I probably wouldn't vaccinate past the first 3 or 4 doses.
Long story short: I would stop vaccinating Midnight entirely and get an exemption for rabies or at the very least only give him the non-adjuvanted rabies yearly. As for your other cats, you probably can't get an exemption for rabies for them but I would only give them the non-adjuvanted rabies yearly as well and forget about the other vaccines.
Vets will push vaccines, it's a core part of their business. The FVRCP vaccine at my vet costs $33 and they also won't administer it without an exam which is $39. I buy an entire package (25 doses) of the same exact vaccine for $60 with overnight shipping and a cooler with ice. They push the vaccines to bring in revenue which allows them to charge less for the more expensive services such as surgery.
