I have a 9 year old black cat, he has been drinking a lot of water lately and has realy bad dandruff. I just thought it was the change of weather. I come home today and his litter box is filled with urine it is like someone put cups of water in it. Can anyone tell me anything? Has anyone had this problem with thier cat? He has a cyst under his left arm, I won't let anyone operate, because I know once they do he is going to have all sorts of problems. He has been fine eats,plays and everything until now. Please Help!!!!!!
