My cat has had fleas lately and Im working on getting rid of them. However whenever I comb him I put the hair and fleas in soapy water there seems to be small amounts of blood. Not a lot but irs not coming from anywhere on him, Ive checked him over and theres no cuts or scratches! What could it be and should I be worried as I only see blood in the water?

Hi there. Flea dirt (which looks like grains of pepper, and is actually flea poop) is essentially dried, digested blood. So in cats with lots of flea dirt in their coat, the bath water will run off as a red or rusty brown color.
