Since gizmo has been sick he has been grooming this one spot continously. I'm waiting to see a bald spot pretty soon. It is close to where his amputated arm should be. He isnt pulling out fur but he is grooming it alot and getting it wet and it sticks out a bit. I've checked it a thousand times and I cannot see anything stuck in his fur. I thought maybe he had squished a poo in it. What is he doing?
