Cat hair, you have birds that take it? As in hair that a cat has shed?  God (or even Keith) please introduce me.  My cat is a perpetual shedder, I’ve no idea how he’s not bald with all of the hair he sheds and the the only logical conclusion is that he’s an alien cat (or perhaps a duck in diguise).  Bring on the birds.  (Note to self: Consider the fact that this may be why i always had birds flying inside my house at the previous address and decide if I really want this again).
