Depends how old. I think Jaguars live something like 12-15 years in the wild, and as much as 23 years in captivity, which makes it possibly the longest-lived cat. Unless you're a accredited zoo or wild animal park, I think it's illegal to own a jaguar in this country, and that's a good thing. I suggest you get a regular pussycat and forget about a jaguar. You didn't mean the car, did you?
