Ask for Cat
It depends what cat you're talking about, if it's your cat and you don't know how old he/she is remember what year your cat was born in and count up to the year now.

there is no way to know exactly how old you cat is but if you take it toa vet they can give you an estimante
"Go" on the floor. If she is acting like she doesn't know you she has probably had a stroke. But what do I know? I'm just a 10 yea old girl.

Maybe he is an old cat
The cat will be 112 in people years. Ok now listen if you would have listened to your math teacher you would know how to figure it out.
A 13 year old cat in cat years is 13 years old... in human years 68 years old.
Er..........none (well I don't know any that do!)
A 21 year old cat is about 101 years old in human years.
It doesnt matter how old you are, the cat is as old as his date of birth to present day.
