Yes, ultrasound would be another option, I guess, even though my vet thinks that an x-ray shot with a "dyed" bladder would be more conclusive. But actually we do not want to put Luna through another anaestesia too soon, as she was suffering so badly after the last one.

But I'm really beginning to worry that it's a tumor. I was told they are rare in cats, but as you see in Peanut, it DOES happen.

I'm sorry to hear that there are still abnormal cells in her urine. How does she live with only half a bladder? Does she have any problems resulting from that?

Best wishes to her!
