Vaccinations for Kittens and Cats

Vaccines are designed to protect your pets from illnesses and boost their immune system. It’s important to work with a veterinarian to determine what vaccines your individual pet needs for maximum protection. At Sims Veterinary Hospital, our team treats each patient according to their needs and unique situation.

What vaccines does my cat or kitten need?

In veterinary medicine, it is believed that all cats should be vaccinated against diseases that have a higher transmission rate and cause severe to life-threatening illnesses. These vaccines are called core vaccines. Feline Panleukopenia (cat flu/ cat distemper), Rabies and Feline Viral Rhinotracheitis (herpes virus) and Calicivirus are all core vaccines for cats and kittens.

Non-core vaccines are recommended based on your cat’s lifestyle or exposure risk. Feline Leukemia Virus is one of the non-core vaccine for cats. Although not all cats or kittens need this shot, it may still be recommended to your pet depending on their unique situation. Kittens under the age of one-year-old and adult cats who go outside are at a greater risk for Feline Leukemia Virus.

When should my cat or kitten be vaccinated?

Kittens should begin their series of vaccines around 6- to 8-weeks-old until they are 16-weeks-old. After a year they are given their first booster shot. Our veterinarians will administer booster shots every year or three years depending on how long the vaccine provides immunity.

Does my indoor cat or kitten need to be vaccinated?

Yes! An indoor cat is not immune to diseases. Your cats can also contract diseases from other pets they come in contact with or from airborne germs.

How are vaccines administered to my pet?

Just like in humans most vaccines are given through an injection under the skin, or into a muscle. Some vaccines may be given as drops through the nose.

Are vaccines safe for my pet?

In general vaccines are safe for pets, however, it’s normal for them to have reactions. Some reactions to look out for include: loss of appetite, vomiting, hives, fever or diarrhea. These side effects are usually short-lived and don’t pose a major threat to your pet’s health. If you become concerned about any of these side effects, reach out to us for instructions.
