My cat seems to have bloody diarrhea. The problem is I cant afford to take him to the vet. I know this isn't normal but I'm curious as to how serious it could be. His behavior is the same. He's still very active and eating and drinking the same. My daughter will kill me if I don't find a way to fix her cat.
(1) Diarrhea with blood in it can be very serious. It can be fatal.
(2) It may be something very treatable, but without treatment very serious, even fatal.
(3) It may be something less serious that is temporary and will possibly resolve on its own, but do you want to take the chance?
I strongly recommend you find a way to see the vet and please take a stool sample with you.
I hope this turns out well for you and your daughter and the kitty.
