Thanks everyone. I know I shouldn't be so hard on myself but he's never matted before. The thing is he is able to bend and groom himself if he wants to. After he uses the litter box he always cleans his bottom. Before he was shaved, I did notice that he barely wanted to move around at all. He would eat and then go to his bed or just sit in the hallway and he looked very depressed and miserable. Now he's walking around much more and seems much happier. He didn't need to be sedated and the normal price is $68 but since he was very matted they had to charge me $15 extra which I didn't mind. Now I'm hoping that I'll be able to keep up with grooming him so he won't mat again. If it gets too cold this winter I may need to look for a small dog sweater to put on him.
