My girl Patty is bleeding out of her butt, off and on. She is 5 and she hasn't been acting herself recently. Shes eating less, Shes been sleeping more, and she has crust around her eyes. I've also noticed that parts of the bottom of her feet are a little red. Idk what to do, shes old. Also I don't have much money to take her to the vet. Any advice?
