Questions
How old is my Domestic Shorthair in human years?
Use the calculator above with your Domestic Shorthair's current age. The AAFP curve treats year 1 as 15 human years, year 2 adds 9 (cumulative 24), then each subsequent year adds about 4 human years.
When is my Domestic Shorthair considered a senior?
From 10 years, whatever the breed: the 2021 AAHA/AAFP Feline Life Stage Guidelines count a cat over 10 as senior. Your vet may suggest check-ups twice a year from then on.
Does this age calculator apply to Domestic Shorthair mixes?
Yes. The AAFP curve is the same for all domestic cats. Lifespan defaults shift slightly toward the breed average if your cat is predominantly Domestic Shorthair; if your cat is a mix without strong breed expression, use the Domestic Shorthair option.
