We adopted Hana from the shelter two years ago. She's been to 3 different vets and we've gotten 3 different estimates for her age. One said 5-7 , another 7-9 and another 10-15. I'm leaning more towards the later, because she showed me actual physical traits that back up her estimate (spots in her irises, beginning of kidney disease, arthitis (sp?)).

My first cat still lives with my mother and she's roughly 16 at this point (we know what year she was born, but that's about it). She's still doing very well, beating up on her companion nearly everyday.
