The American Association of Feline Practitioners (AAFP) defines six feline life stages: Kitten (0 to 6 months), Junior (7 months to 2 years), Prime (3 to 6 years), Mature (7 to 10 years), Senior (11 to 14 years), and Geriatric (15+ years). The human age equivalents in this calculator align with that framework.
Spayed and neutered cats tend to live longer than intact cats, by an estimated 1 to 3 years. This calculator provides a baseline. Your cat's actual biological age may vary based on health history.
Yes. The oldest documented cat (Creme Puff, from Austin, TX) lived to 38 years and 3 days. Indoor cats with good care regularly reach 15 to 20 years. Exceptional cases reach the mid-20s.
Most veterinary organizations classify cats as 'senior' starting at age 11. At this point, more frequent vet checkups (twice yearly) are recommended. Geriatric status begins at 15.
