My Spencer is sick again - this morning I checked the litter box and found bloody diaherra on the side of the box. I know it's Spence - right now his fur does not look good and he's extremely mopy. I just had him into the vet a couple weeks ago because of blood in his vomit - now this. This cat is a walking health problem!!!I wonder if he has eaten any dog food which may have caused this trouble - anyway it's vet time again.
