Q. My cat has a mass in bladder. Don't know if cancer but probably. He was peeing blood for months, now clear again. What does this mean?
DR. MASSIMO ORIOLES, DVM, MRCVS
A. Probably whatever is the nature of the mass is either bleeding intermittently or create intermittent inflammation.
More investigation are needed to understand the nature of the mass. An abdominal ultrasound would be certainly beneficial in this case. Urine analysis can give you some informations as well (even though the presence of too many red blood cells can make it not very useful!).
