my cat is on innova dry food, which is supposed to help the coat, but last night i was petting him and i noticed that a lot of loose fur was gathering by his tail. the hair is thick and straight, so i think it's the outer coat. i continued petting him and it kept coming out. i examined his coat and found that the fur comes out VERY easily. i am going to brush him later, but is this common? i think i am going to take him to the vet on tuesday b/c he sneezed, too. he's still active and playful. affectionate and attention seeking. he's my first cat so i need advice. if this could be the result of a serious health issue, i will take him to the vet sooner. do they shed more in early spring?
