Rabies
Indoor animals can escape or encounter a bat inside. Rabies is fatal, affects people, and vaccination is regulated by local law.

INDOOR IS A LIFESTYLE—NOT A DIAGNOSIS
The safest plan anticipates ordinary surprises.
Indoor living can greatly reduce contact with unfamiliar animals and some pathogens. It cannot eliminate every route of exposure, legal requirement, household change, emergency evacuation, boarding need, or accidental escape. The aim is to match protection to credible risk—not to label every indoor pet the same.

01 · CORE STILL MATTERS
Some recommendations are not based on outdoor recreation
Feline core protection
Panleukopenia virus can persist in the environment, and cats may face exposure during evacuation, boarding, veterinary care, fostering, or a household change.
Canine core protection
Distemper, parvovirus, adenovirus, leptospirosis, and rabies are serious enough that current American Animal Hospital Association (AAHA) guidance broadly recommends core protection regardless of a quiet home lifestyle.
02 · HOW EXPOSURE HAPPENS
The home is connected to the outside world
- Shoes, clothing, carriers, and objects move between environments.
- Rodents and wildlife enter yards, garages, patios, and sometimes living spaces.
- A pet can slip through a door, screen, leash, or damaged fence.
- Storms, fires, repairs, hospitalization, travel, or family emergencies can make boarding or evacuation necessary with little warning.
- A new pet, foster animal, visitor’s pet, or move can change exposure overnight.
03 · WHAT MAY DIFFER
Lifestyle still changes noncore choices
A truly low-contact pet may not need every available vaccine. The decision should be explicit and revisited rather than based on the word “indoor” alone.
- Adult feline leukemia virus (FeLV) vaccination depends heavily on contact with cats of unknown or positive status and escape or outdoor potential.
- Bordetella and canine influenza become more relevant with boarding, daycare, grooming, group training, shows, shelters, or outbreaks.
- Lyme vaccination depends on tick geography and exposure, alongside year-round tick prevention.
- Health status, immune-suppressing medication, prior reactions, and age can alter timing or product selection.
04 · ANNUAL REVIEW
Ask four questions every year
- What has changed in the home, neighborhood, travel, or animal contacts?
- Which vaccines are legally required, broadly recommended, or specifically lifestyle-based?
- What does each vaccine protect against, and what is its booster interval?
- Is there any prior reaction or current illness that changes today’s plan?
Important: An annual vaccine review does not mean every vaccine is automatically given annually. It means the risk assessment is updated and due protection is identified.
