If you do not vaccinate your indoor cat, they remain at risk of catching serious or fatal diseases that can enter your home.

Hidden Risks for Indoor Cats

Carried on shoes and clothes: Viruses like panleukopenia (feline distemper), calicivirus, and herpesvirus can hitchhike inside on your shoes, clothing, or hands.
Accidental escapes: If your cat slips out the door or a window screen tears, they face direct contact with outdoor animals.
Wildlife encounters: Bats, mice, or bugs can get inside your house and expose an unvaccinated cat to rabies.
Legal requirements: Many local laws require a current rabies vaccination for cats, regardless of whether they live indoors. If an unvaccinated cat bites someone, local rules may force a strict quarantine or mandatory euthanasia for testing.

Core Vaccines Recommended for Indoor Cats

FVRCP: Protects against feline viral rhinotracheitis, calicivirus, and panleukopenia (distemper). Veterinarians consider this a must-have for all cats.
Rabies: Protects against a 100% fatal virus that spreads to humans.
