I'm wondering if anyone else has ever experienced this. Kylah pulls patches of her own hair out. She only does it when she is home alone, never when we are home. She started back by her tail, so we took her to the vet and they gave her a cortisone shot and 2 weeks worth of antihistamines (they thought it was a hypersensitivity reaction). After that didn't work, I decided to try my own method and I started spraying bitter apple spray on the areas she was bothering. That worked great, but after about a month, she started moving to other parts of her body. I'd love to figure whats going on, all I can think is that she is possibly doing it out of boredom?
