Elderly, I rreckon around 15.............Kocka lived to 20 but started going downhill around 16.
My birmans are 17 and acting like elderly kittens at the moment but both have problems.
Sasa is 11 and could be older but apart from a new issue she has never been ill
Misa I am horrified to realize is now 9 and cant believe he is that age, still a big kitten although much wiser now then when he was 4 LOL
