I called the vet and she said its normal that he's doing the litterbox jumping right now. Carla, by litterbox juming I mean he tried to pee in one box, nothing comes out so he tries another. The vet asked if he's peeing in the boxes.... ummm... no, but I think its because he just had a catheter removed and nothing's in him to pee. He did drink a lot from the waterfountain. Lets hope pee comes out in half an hour or so.
