That wouldn't surprise me! Mind you, aren't all 5 month kittens a bit naughty?
I guess I was just curious - I know that orientals are renowned for a particular temperament, as are ragdolls etc., but I had never heard of non-purebreed cat types having specific character traits until I cam across this mention of the "tortie temperament"
Thankfully, my little girl is also a real sweetie, so even if she does become really cheeky or naughty, I'd end up letting her get away with it anyway! lol
