I am going through a very similar problem right now, only I take my own actions and his health into consideration and dopn't blame the cat. The majority of peeing problems can be remedied through problem solving: why is he doing it? Is it because his litterbox isn't up to his standards? Is it an underlying health problem more than an UTI? When my Pouncer kept peeing and the vet saw no crystals but did see blood, he had chronic cystitis and it took months of steroids and antibitoics to clear it up. We actually have to go back for a recheck next week.... someone has been peeing around here and he's suspect #1.

When my Allen was peeing it was because he thought his box needed to be scooped more than once a day. He also did NOT like the perfumy litter, so I replaced the Fresh Step with an unscented litter. Then he started peeing because we added a second cat but not a second litterbox. Truthfully, two cats need 3 litterboxes, somethign I thought sounded absurd until I added my 3rd box and then I wondered why I was so stubborn about adding that 3rd box.

Allen also peed this past fall because he was mad at me for closing off "his" room when my son went off to college. He peed on anything and everything for two weeks. Then it dawned on us that the peeing coincided with my son leaving and we opened the bedroom door...... and the peeing stopped immediately. He just wanted his room back!

All it takes is a little detective work to find out why your cat pees. Allen sitll pees, but only in a laundry basket... and shame on me for leaving it out. I know thats what he does, and I should take away the temptation when its at all possible.
