A friend of mine has the most beautiful Persian exotic chinchilla. (Rescue) she's quite standoffish but will go to him for fuss. She's short haired but has a thick coat, and has got a large Matt on her back. She will not allow anyone to groom her. When I tried she turned into a hissing spitting bundle of claws and teeth. And I have a hole in my finger, Where she bit me. It looks very uncomfortable for her. The groomer who did my girls won't cover his area and struggling to find another one who covers his area. He's reluctant to take her to the vets as she also freaks getting her in the basket. Any ideas anyone? I've never seen a cat behave like that. We suspect something very bad has happened in the past.
