Have Cat Questions? Ask a Cat Vet Online.
Hello, this is Dr. Jess. I am sorry to hear about your cat. Can you tell me how her urine is appearing? Is she still drinking? Is she lethargic? Any vomiting?
And she has brown discharge from her mouth? Will she allow you to examine her mouth? Are her gums pink in color or are they pale? Can you see if any of the teeth look infected? Red at the gum line or discharge present there?
So it looked like blood coming from the mouth?
Ok. I am very concerned then, that she has a systemic illness that could be affecting her liver or red blood cells. Discolored urine can be a result of blood in the urine as well as a byproduct of red blood cells or muscle cells that have been destroyed themselves in the body. Your kitty is definitely in need of a veterinary exam and bloodwork to check liver values and red blood cells to check for serious systemic disease.
