I know you didnt post to hear about choice of food for kitty, but I have to agree with alot of what is being said about food for kitty. I fed my cats walmart, friskies etc. forever then I lost my 12 year old to kidney failure and when I brought in 19 year old for check up right after that vet said she was beginning stages of kidney faliure. This, I was told, is due to kitty eating poor quality foods for so long. My 19 year old is stable now and eating expensive K/D and Renal LP...HOWEVER, after all my trauma with my old kitties Ive taken the advice and my new kitten gets "MAX CAT" brand foods from PetCo. They arent TOO expensive, couple dollars more per bag and every ten cans or so. Probably costs me an extra 20$/month overall. I was told they shouldnt be feed anything that is 'by-products'. You should check ingredents
...NOW as for the biting out fur thing....I had a friend whose cat did that. I used to see the cat all the time and he seemed OK except for that. Their vet told them it was a sort of behavorial thing and that cat was/had schitzsophrenic/ OCD (over compulsion disorder) or something like that....this may or may not be true and sound like a quack, but I would always see the cat when I visited and he seemed ok, with exception of that. Kind of makes sense too with the OCD, he cant seem to be satisfied with cleaning himself, he keeps doing it over and over.
