I have read thru the other threads, but, seem unable to find an answer that specifically pertains to my problem. Some have slightly touched on it but, not exactly. Boots, my neutered 1 yr. old tuxedo cat has recently inexplicably started to use my bed as his litter box. This has happened 5 times. He not only urinates, but, also defecates as well. He has always shared the litter box with Lenny, my 6 yr. old spayed Himalayan. In a years time, I have never had any problems at all, until about a week and a half ago. The litter has not been changed, there has been no changes in household or anything out of the ordinary. I am going to buy a new box, even though this one is only 5 mos. old to see if that is the problem. They have a box in kitchen, one on 2nd floor, and a third one in basement. Any suggestions? Also, I keep them very clean. We love him dearly, and want to solve this because I really think of him as one of the family. Thanks. Sincerely, Renee
