...we have is approaching 16 or 17 years old. He's still in good spirits. Always indoor, and very social. Always in whatever room we are in. As he's getting older he's starting to get closer and closer to my wife..... I dread the day he croaks, not for him, but I know my sweetie will be absolutely crushed. (She's actually researching cloning him......it's "only" 28 large..... I have a problem.)
Cloning won't get you the same cat, just the same DNA.
And it'll be an old cat. A small old cat, but an old cat. It won't live long.
