Frequently Asked Questions
- How old is my cat in human years?
- Year 1 ≈ 15 human years, year 2 ≈ 24, and each year after adds roughly 4 human years. So a 10-year-old cat is about 56 in human terms.
- What is a 'senior' cat age?
- AAFP/AAHA classify cats as Senior from 11–14 years and Super Senior at 15+. Biannual vet checkups are strongly recommended from age 11.
- Does breed affect cat aging?
- Unlike dogs, breed size in cats has less impact on aging rate. However, larger breeds like Maine Coons may mature more slowly. The standard curve is accurate for most domestic cats.
