Do you have other cats? One of them could be sabbotaging the other while in the box and that's why he's doing it. Did your vet test for crystals? Just because there's no blood in the urine does not necessarily rule out a UTI.

Rule of thumb is one litterbox per cat per household. If you have more than one cat and only one box, that could very well be the problem.
Thanks for the quick reply! I do have 2 other cats. However, I have 4 litter pans out--1 for each cat, plus an extra. I haven't changed the litter type, box location, or food type, so it's not an environmental change.

My vet did not check for crystals--in fact, he didn't do any actual tests for an UTI because of the lack of fever. On the way to the vet, poor Mr. Darcy peed himself in terror, so the doctor couldn't feel his bladder. I don't know if feeling his bladder would be a test for crystals? To be honest, I just don't know enough about bladder infections in felines.

Hmm, interesting proposition. One of our cats--the youngest and smallest of them all--did start harassing him while he was using the pan the other day. At first I thought it was just because he was marking outside of the pan and Phoebe (the kitten) was being possessive (she is female, though, and I don't know if she would react the same way as a male would). She jumped into the litterbox he was using and urinated alongside of him, which agitated him enough to make him get into the other pan.

I'd never seen her do anything like that before, and I haven't seen her be aggressive like that since then...however, the litter pans are out of my site (in the garage, downstairs), so I may have missed it.
