ok, my cat who is about 10 months old got out side and when he came back in he had this peach colored greezy stains on his fur on the back of his neck and down his spine in spots and i noticed this last night and didnt think anything of it. now i was petting him and his hair is falling out where this greasy things are!! what should i do, what if its poison? or maybe someone put that cheap hartz flea medicine on him. if they did, that can kill him i heard horror story of that product. hes acting completely normal. what should i do??? please i rather not go to the vet quite yet, but if i have to i will
