Last week we discussed Feline Aids and whether you should vacinate.  Approximately 12% of all cats have Feline Aids.  Although Feline Aids can be terminal, FIV is not as a death sentence like it is in humans.  Infact, cats can test positive for aids and never manifest the disease.

In 2002 Fort Dodge Animal Health released a vaccine designed to prevent a healthy cat from acquiring Feline Aids. The drug is controversial for several reasons.

1.There are at least five known strains of FIV. The drug does not protect against all strains. Cat guardians may feel secure that there pet is protected, but in fact, the pet is only protected from certain strains of the disease.

2.Once you vaccinate a cat for FIV, it will always test positive for FIV. This means that a veterinarian can not tell the difference between a healthy cat vaccinated for FIV and a cat infected with FIV. If your healthy cat was vaccinated to protect against FIV, and later is infected with FIV and becomes ill, it is impossible for a veterinarian to know if your cat is infected with another strain of the illness. This makes treatment challenging.

3.The FIV vaccine is an “adjunctive” medicine. One of the common side effects of “adjunctive” medicine is the growth of tumors.

4.Lastly, the FIV vaccine has a success rate of 82%. This means that one out of five cats exposed to FIV will contract the disease, even if they were vaccinated with the drug.

Here are a few things you may want to keep in mind. If you have an indoor cat and it’s not exposed to other cats, it can catch viral diseases such as Leukemia, but it cannot contract Feline Aids. There is no need to vaccinate an indoor cat against FIV. If you have a cat that spends time outdoors, make sure it’s spayed or neutered before sexual maturity (approximately six months). This is the first line of defense. Your cat will be far less likely to be involved in a cat fight. This greatly reduces the chance of a bite, or blood-related injury with an infected cat. If you decide to vaccinate your outdoor cat, make sure it also has a microchip and collar that identifies you as the owner.

If your cat was ever picked up as a stray, and the shelter could not easily find the owner/guardian, your cat would be euthanized quickly since it would test positive for FIV. If your cat contracts FIV, this does not mean a mandatory death sentence. Most indoor cats with FIV can live a long and reasonably healthy life. Lastly, be assured—there are no known incidence of Feline Aids effecting humans or dogs.
