Core Vaccinations: The Must-Haves

Feline Herpesvirus (FHV-1) and Feline Calicivirus (FCV)

These two viruses cause cat flu, a nasty respiratory infection that can make your cat feel miserable. Even if your cat doesn’t step outside, these viruses can sneak in on your clothes or through a window. A quick jab helps keep these illnesses at bay.

Feline Panleukopenia Virus (FPV) (aka Feline Distemper)

This is a big one. FPV is a severe, potentially fatal virus that can cause vomiting, diarrhea, and immune system problems. It’s highly contagious and tough to get rid of once it’s in the environment. Vaccinating your cat is the best way to ensure they’re protected.

RabiesUS

Rabies is a deadly virus that can affect all mammals, including humans, and in many US states, it’s required by law to vaccinate your cat—even if they never go outside.

UK: Rabies isn’t present in the UK, so it’s not a routine vaccine unless you’re planning to travel with your cat abroad.

Non-Core Vaccinations: Consider Them Depending on Your Cat’s Lifestyle

Feline Leukemia Virus (FeLV)

FeLV is a tricky one. It’s a virus that suppresses the immune system and can lead to serious illnesses. If your cat ever meets other cats—whether through a screen door, at the vet, or if they sneak outside—this vaccine is a good idea. Even for indoor cats, some vets recommend it just to be safe.

Chlamydophila felis

This vaccine helps prevent a bacterial infection that can cause eye and respiratory problems. It’s especially recommended for households with multiple cats.

Bordetella bronchiseptica

More common in crowded conditions like shelters or multi-cat homes, this vaccine protects against a respiratory infection. It’s not usually necessary for a solo indoor cat, but if your cat is ever exposed to others, it’s worth considering.
