VI. Cats - Health: Vaccinations

When your cat was born, she received protection against many infectious diseases from antibodies passed in her mother's milk. But these antibodies dissipated by the time she was 3 months old, leaving her immune system vulnerable. Fortunately, effective vaccines are available that can protect your cat against many diseases.

How Do Cat Vaccinations Help Your Cat?

Vaccines contain modified live or killed viruses. These don't cause the illness, but stimulate an animal's immune system to protect her from the real thing. Veterinarians recommend that kittens receive their first set of vaccinations at six to nine weeks of age. Combination vaccines are available that protect against feline calcivirus and feline rhinotracheitis, both respiratory diseases, and panleukopenia. Also known as feline distemper, panleukemia is very contagious and can be fatal, especially to kittens. This three-in-one vaccine can be given as an injection or as eye or nose drops, which eliminate the pain associated with needle injections and provide rapid and more complete immunity to upper respiratory viruses. No matter which form you choose, you'll need to bring your animal back to the veterinarian in three to four weeks for a booster vaccination.

Feline Vaccinations Protect Your Cat From a Variety of Illnesses

Vaccination against rabies also is important-and in many parts of the country, it is mandatory, as rabies can be transmitter from animals to humans. This fatal viral disease can be transmitted through contact with an infected animal, so protection is crucial for animals who are allowed outdoors. Veterinarians recommend that kittens receive their rabies shot at three months of age. Your cat will need to be revaccinated once every year or three years, depending on the kind of vaccine she is given and the vaccination requirements in your area.

Another killer you can protect your cat against is feline leukemia. This deadly virus attacks a cat's immune system. Vaccination is essential for outdoor cats, who are at much greater risk of exposure to feline leukemia than indoor cats. If your cat remains indoors and is not exposed to other felines, you may want to discuss with your veterinarian whether or not vaccination against feline leukemia is necessary. If your animal has been vaccinated, boosters must be given every year to provide full protection.

Vaccines are available to protect against other diseases, such as chlamydia, feline infectious peritonitis and ringworm, but veterinary opinions vary about their usefulness. Check with yours to see if they are recommended for your kitty.

Monitor Your Pet For Allergic Reactions to Cat Vaccinations

In some cases, vaccines can cause adverse reactions, including allergic reactions that will require immediate veterinary care. Other symptoms may include listlessness, appetite loss and mild fever. If you notice any of these signs, monitor your cat and call the veterinarian if the symptoms do not clear up after a few days. You may also notice a small, firm swelling at the site of the vaccination. This will usually disappear within a short time.
