Why is my cat peeing dark, bloody urine on blankets but not in pain?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 4 lbs

My wife and I found Luna peeing on a blanket today, and we noticed the urine was a very dark color(maybe blood). We found her peeing on a couple other blankets as well. She does not seen to be in pain, but this still catches our attention. What can this be?

Hi, and thanks for your question. These signs might be compatible with a urinary tract infection/inflammation. Stress related (idiopathic type of inflammation) infection and presence of crystals are the most common causes of it. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
