Average life span of cats

I hear is 10-15 years. Does anyone know or have had a cat that lived longer?
Suddenly today Im petrified of my cat dying. I shouldnt be thining about it I know, and sorry to be morbid
My cat is 9 and completly healthy yet I worry

My baby girl Miniboots died 6 months after her 21st birthday. If they're indoor and taken care of they have long life spans!

My childhood cat, Happy, who was indoor/outdoor was put to sleep at 19.5!

I know how you're feeling - my little Pookie is not even two - and I freak out at the thought. Hopefully, our babies will live long full lives!

I have read about cats living until 22 years of age. MY dh grandmother had a cat that lived until 18.

I can't even think about the day whe my cats die.

Lets hope all our babies live long and happy lives.
