As I have found he has a nasty infection in both ears which has been neglected, it's possible he was trying to tell them his ears hurt and was being ignored. He is very gentle and friendly and let me put drops in his ears with no fuss and appears a lot more comfortable already. We will get his ears checked at the vet asap though.
Awww, Twister! I've had an ear infection too and it hurt a LOT, and that was just in one ear! I'm glad you are more comfortable now and I hope the infection goes away very quickly. Welcome, sweety!
