My female cat has urethral bleeding and two fleshy translucent masses – what organ and what disease?

First distinguish whether blood comes from the urethra or vagina. Urethral bleeding suggests urethritis, bladder stones, or bacterial cystitis. If an unspayed cat urinates normally, blood may come from the vagina or uterus, such as vaginitis, pyometra, or fibroids. In all these cases, take the cat to a nearby pet hospital for urinary and reproductive imaging and blood tests to confirm the cause, then treat accordingly; severe cases require surgery.
