My Wrinkles has tortitude. I had her and Cleo in the sturdi shelter together at the show. Cleo stepped on her to get in the bed and she hissed and clawed her.. If Wrinkles is playing with the other cats and they get to rough she will hiss and claw them. She is good in the ring at the shows but thinks she is the boss at home. Cleo has a scratch on her neck now.
