Hi, Just thought I would share a similar experience I recently had with a ferret and bloody urine... I noticed red on the floor when one of my females, a 3 y/o sable named Daisy, was peeing in her favorite corner one evening during free roam playtime - I thought it was all blood, but upon closer inspection, I saw it was blood mixed with urine. That area where she pees from was red and obviously irritated too, causing more discomfort. I took her to the vet the next morning. Immediate possibilities ranged from urinary tract infection, to stones in her bladder. He started her on antibiotic, and Xrays were done to determine if there were stones present - and discovered that she had 8 stones in her bladder, as well as a urinary tract infection. The stones were removed a couple days later. She did very well with surgery, and was home that same day. That's the only time that I have seen blood in a ferret's urine, and yes it freaked me out, especially because it happened at night, after the vet had closed for the day lol.
