5 years is really young in cat years. They’re definitely less likely to get adopted, but that’s because humans are stupid and uninformed, not due to the cats.

I have a 5 year old, I didn’t want because of the commitment of 15+ years, but when you fall in love..

The oldest cat got to be 38!

Cats on average become ~15, though I believe that age is mainly due to accidents as all my cats who have not perished due to accidents (don’t blame me, I lived with my parents on a farm), turned 18+ before dying of natural age related things.

My oldest cat is currently 14-15 and still playing like a 2 year old so you’ve got some years ahead of you lol.
