It was quite obvious something was wrong, he started by peeing outside of his litterbox and that escalated to licking himself and growling, crying while trying to pee, and trying to run away and dig away from the pain in the garbage cans. I took him in right away and they took a urine sample and tested it right away. It was caught early so he ws on canned food for a couple weeks with no dry and pills twice a day.
You'll know right away if they develop them, I hear its quite common in male cats, poor boys!
Take care
