What Is the Indoor Cat Life Expectancy Calculator?
The Indoor Cat Life Expectancy Calculator estimates how long your indoor-only cat is likely to live. Indoor cats consistently live longer than outdoor cats because they avoid traffic, predators, disease exposure, and fights with other animals.
Every result is based on published veterinary research and veterinarian-reviewed formulas — not generic averages. Completely free, works instantly, requires no account or sign-up.
