My dad realized that one of our cats are bleeding... out their bum... my dad thinks it their food. I do not belive it for a second. I don't understand how there could be blood in the pan, and even a drop on the floor from their food. Right now they are trying to find out which cat it is. I think that the cat (when they find out which one) needs to get to the vet ASAP. I'm trying to tell them that i know more about this then they do, but they always have the "we'll wait and see" attitude. I know that cats bleeding like that isnt normal. But, any suggestions on what it could be.
