My senior cat is peeing blood, has black discharge. Should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | Persian | Female | unspayed | 16 lbs

My cat has the tendency to pee everywhere but her litter box and I noticed that she was leaving small blood spots wherever she sat. I also noticed a small amount of blood in her bowel. But recently she was walking and I noticed her vagina area was like black. She’s about 12 years old and never has been to the vet. She’s also an indoor cat, always has been. Should I be concerned?

Yes I would be concerned about Lacey. It's not normal to leave small blood spots where she sits, nor is it normal for her to have blood in feces. The black color of her vagina area is concerning as well, as that could be dried blood. There could be a number of reasons for her symptoms such as a UTI, pyometra, GI ulcers, or GI tumors to name a few. She should see a vet for these problems, and I would take her into one first thing in the morning. Best of luck!
