I have heard that cats like to have their OWN litter box and may not use one that another cat is using. A cheap experiment would be to give your problem cat its very own litter box, with some initial coaxing and/or confinement to get him/her to use the box first, before the other cat gets to it. Locate the new box far from the old(other cat's) box. Rich Ganns hou2a!murphy
