Kblaix - thank you! It isn't all the time at all like maybe one time was a week ago, now and then over a month ago. Meka is stressing him out bad. She keeps cornering him. I found him in the bathtub the other day by his litter and I wondered why he was sitting there. I walked twoward him and Meka was crouched by the toilet ready to pounce when he moved...... They both use the two litter boxes. They both want to put their mark on each one so it is so hard to tell which cat is doing what... Really it is my fault because we are not home much anymore. That could also be doing it - stressing them out. I'll keep a better eye on them both. Thanks again, Debbie
