We got a pair of cats 19+ years ago - brother and sister. The sister got run over a couple of years ago. Our cat - (his name is Cat) - is an outdoor cat although he sleeps, eats in the garage every night. During warm weather he is outside. During the cold, wet winters he spends practically all of his time in the garage.

He is getting very slow and old. We keep waiting for him to go, but he still must have multiple lives left. We haven't taken him to a vet for 3 or 4 years now as we keep expecting him to go on to cat heaven, but he keeps plugging along. He walks very slow and gingerly - and you can tell he is a very old cat. He is also pretty much totally deaf too.

How much longer should I expect him to live? I thought 15 - 16 years was about the expectation for an outdoor cat, but he keeps plugging along.
