Hi everyone, I could use some advice. About 2 weeks ago, after floor time, I noticed that there was blood on the floor. (We have dark fleece and didn't know how long this was going on.) I took both girls to the vet's office, because I wasn't sure who had the blood. The vet took urine and determined that both had blood in their urine. While he was surprised to find blood in both, he determined that it was a UTI. He gave them both shots and put them on antibiotics for 10 days. After 10 days, we stopped the medicine. (We put paper towels down in the cage and there was no blood.) Now, 4 days later, (again after floor time) we noticed more blood. I have enough medicine to start the medicine again. Should I take them back to the vet? Is it weird that there is only blood after floor time?
