Do Indoor Cats Need Vaccines? (Yes, and Here’s Why!)

Even if your cat spends their days lounging on the sofa, stretching out in a sunspot, or observing the outside world solely through the window near their cat tower, they still need vaccines!

Exposure to dangerous and even deadly diseases can occur in unexpected ways, meaning indoor cats need vaccines just as much as their outdoor counterparts.

Why do Indoor Cats Need Vaccines?

Vaccines work by introducing a modified, inactive, or tiny amount of a virus or bacteria to the immune system, allowing our bodies to recognize an illness and learn how to fight it off. If a vaccinated cat then encounters that virus or bacteria in the wild, their body knows how to respond so they don’t get sick.

Vaccines are safe, effective, and protect more than just individual pets. The more vaccinated pets there are, the less opportunity there is for disease to spread through animal communities.

Viruses and bacteria are pathogens, which are microorganisms that can cause disease. Pathogens can travel in a multitude of ways, including by sticking to surfaces, clothing, or even skin. Some pathogens can even be airborne. This means that even if your cat is exclusively indoors, they could still be exposed to diseases that hitchhike through open windows, on objects you bring in the house, or even on you!

Indoor cats need vaccines because the unexpected is worth preparing for, especially when it could mean life or death. Vaccines provide both vital protection for your pet and peace of mind for you.

Core Vaccines vs Others

Core vaccines are a category of vaccinations that are strongly recommended or even legally required for our pets. Indoor cats need vaccines from this core category, which include FVRCP and Rabies. Both of these vaccines prevent severe or potentially deadly diseases, which are unfortunately common and difficult or impossible to treat if contracted.

Vaccines outside of the core two may be recommended for cats at higher risk for illness. For example, though FeLV should be administered to all cats under a year old, annual boosters may only be needed for cats at high risk of exposure. A veterinarian may recommend additional vaccinations based on a cat’s health, age, and additional risk factors.

When Should I Vaccinate My Cat?

Both outdoor and indoor cats need vaccines throughout their lives to remain healthy. Kittens should be given their initial vaccines starting at 8 weeks of age. These shots continue in a series until the kitten is 16 weeks old. FeLV is considered a core vaccination for cats under 1 year old and should be administered accordingly.

Adult cats need annual or tri-annual boosters to ensure their protection remains in place. Cats at higher risk for disease may need vaccinations more frequently. Alternatively, they may need vaccines outside of the core set to stay healthy and happy.

If you have questions about which vaccines are right for your cat and when they should be given, speak with your veterinarian. They can help you choose the correct plan for your pet’s health.
