Fred - those are some good ideas and we have tried modifying the areas around the litterboxes to accomodate him. But at one point, the problem was continuing even when he was isolated to one room with his own litter box. Shadow is the alpha cat in our house even though he doesn't seem to realize it at times. The other 2 cats will run away from him when he starts pouncing them. No other cat is bullying him in any way.

MarnaLou - we have heard that as well. We'd have to find space for another 2 litter boxes in the house. :) We have 2 LARGE litter boxes as is ....

Marcie - very true. If Amanda and I were taking the Prozac, we'd probably not care about the fact that he was peeing in the laundry sink. :D
