My sweet fifth-teen year old girl, still has quite a bit of fight left in her whenever I touch her belly for to long. For being fifth-teen she’s quite healthy, still having quite a few bunny kicks left in her. I don’t think I’ll stop petting her belly anytime soon as her reaction is so cute, thinking her little paws could do me any harm
Our 15yo tortie was like that too. Every time the doc saw her he’d remark that if he didn’t know any better he’d guess she was 6-8. She was more active than our 3-4yo cats which I always found funny.
