HiCustomer Thank you for asking your question on Just Answer. The other Experts and I are working on your answer. By the way, it would help us to know:Is the blood in his mouth ot just around it?
Has he been vomiting?
Does he have dental problems?
Do you have rodenticide around the house?
Is he an indoor or indoor outdoor cat?
When did this start?
Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.
The blood around your cats mouth could be from a bad tooth, from him scratching his muzzle(especially if something is stuck in his mouth), a rash, a cut in his mouth. He could be bleeding from his mouth or nose from ingesting rat poison.
With out seeing the blood I have no way to know how much or where it is coming from.
I would strongly suggest you seek out your regular veterinarian if you can and have your cat looked at.
He could have scratched his muzzle. Or have a bleeding issue like from poison or an autoimmune issue like thrombocytopenia(low platelet counts).
It is also possible he got into something that caused an abrasion on his face. I have also seen a few cats with URI infections bloody their face.
I would not fool around with this. You can try to look for a cut or lesion on his face mouth or tongue. Look for little red splotches on his gums. But if he is actively bleeding get him to a veterinarian ASAP.
