Feline Vaccinations Vaccinations are one of the best ways to protect your cat from serious infectious diseases. Vaccines work by safely stimulating your cat's immune system to produce protective antibodies. If your cat is later exposed to a disease, their immune system is prepared to fight the infection or reduce the severity of illness. Every cat has different vaccination needs based on age, health, lifestyle, and risk of exposure. Our veterinarians will recommend a vaccination schedule tailored specifically to your cat.
Why Does My Cat Need Vaccines? Vaccines protect against diseases that can cause severe illness or even death. They also help protect people from zoonotic diseases such as rabies. Even indoor cats should remain up to date on their vaccinations. Cats can still be exposed to disease through travel, boarding, new pets in the household, wildlife such as bats, or viruses carried into the home on clothing or other objects.
Kitten Vaccinations Kittens receive temporary immunity from their mother's antibodies, but this protection gradually fades during the first few months of life. Because these maternal antibodies can also interfere with vaccination, kittens require a series of vaccines to ensure they develop lasting immunity. Vaccinations typically begin at 6–8 weeks of age and continue every 3–4 weeks until at least 16 weeks of age. Completing the full vaccine series is essential for proper protection.
Booster Vaccinations After the kitten series, booster vaccines are needed to maintain protection. The timing of boosters depends on:
Your cat's age
Overall health
Indoor or outdoor lifestyle
Risk of exposure
The specific vaccine
Rabies Rabies vaccination is required by New York State law, and we will recommend the appropriate booster schedule based on your cat's individual needs.
Vaccine Reactions Most cats experience no side effects after vaccination. Mild reactions such as soreness, tiredness, a mild fever, or decreased appetite for 24–48 hours are normal. Contact us immediately if your cat develops:
Facial swelling
Vomiting or diarrhea
Difficulty breathing
Collapse
Persistent lethargy or signs lasting more than 48 hours
Serious vaccine reactions are uncommon but require prompt veterinary attention.
Core Vaccines FVRCP (Feline Distemper Combination Vaccine)FVRCP is the core vaccine recommended for all cats. It protects against three highly contagious diseases:
Feline Viral Rhinotracheitis (FVR): A herpesvirus that causes upper respiratory disease and can lead to chronic eye and respiratory problems.
Calicivirus (C): A common respiratory virus that ranges from mild illness to severe pneumonia.
Panleukopenia (P): Also called feline distemper, this highly contagious parvovirus causes severe gastrointestinal disease and is often fatal in young kittens.
The FVRCP vaccine is highly effective at preventing these diseases.
Lifestyle Vaccine Feline Leukemia (FeLV)Feline Leukemia Virus (FeLV) is a contagious viral disease spread primarily through close contact with infected cats, including grooming, shared food and water bowls, and from mother to kittens. Although FeLV is considered a lifestyle (non-core) vaccine, it is recommended for all kittens and young cats, and for any cat that goes outdoors or may have contact with cats of unknown FeLV status. Cats should be tested for FeLV before their initial vaccination.
