Not sure I have asked this question here before or not but I have a problem with my cat eating the dog's bed. It's a real soft fur bed. It's looks like this...

My cat is eating mainly the top edge of it. I have used everything under the sun to spray it and she just keeps right on going back to eating it. We have done it all, sprayed the bed with smelly stuff, chased her and sprayed her with water. Nothing seems to work. She will even eat it when the dog is on there sleeping. I'm beginning to think she has OCD. 2 Years ago she developed Feline Hyperesthesia Syndrome. That was shortly after another cat came into the house that she doesn't really like. She avoids him as much as possible.
What happened was, my son's girlfriend (at the time) had placed her cat at her Mom's house while she lived with us. We didn't want to take him in because we already had 2 cats and a dog. Needless to say, after her Mom had the cat for one week, she threw him out the door. She hates cats. We ended up taking him in till she found a new place for him. Unfortunately for the cat, when her Mom threw him outside, he got in a fight with another animal and ended up with a hematoma on the inside of his ear. When we got him, his ear was swollen and the skin was puffed up so that you could not even see inside his ear. We took him to our vet and they drained the fluid. Sadly his ear never stood up again. Well, that was 4 years ago and she is no longer even in our lives. He's really a love with people but, he and our female cat just do not get along. We have tried finding a new home for him but, no one wants an older cat. I haven't the heart to bring him to a shelter because prior to us, he went through 3 different homes plus I don't want him put to sleep.
Both he and the female basically ignore each other except, now our female cat has developed FHS and now I think OCD. At any rate, is there anything we can use to get her to stop eating the bed? I have already made a slip cover for it and that seems to work but, it's not as soft as the cover that's on it. I don't have a problem with a slip cover but my husband seems to think it's a problem and the dog would rather sleep on the soft fur. (GMAFB) LOL Any suggests are appreciated.
My next step is contacting Jackson Galaxy ( from My Cat From Hell) LOL
