I just got a 4 month old Kitten from the animal shelter about a week ago. He does not groom himself. The only time i have ever seen him clean himself is his privates after using the litterbox. The shelter said he was a stray, and infested with flees when they found him. He does not have flea's anymore, and also got a clean bill of health from the vet. Is there anything that can be done or any advise. This is the first time I have seen this. Other than that, he is the most lovable and sweet little thing!!!
