Cats are generally curious and tend to investigate new things. Those already familiar with a covered litter box may be quicker to investigate. We recommend placing the Litter-Robot where the old litter box used to be, especially if your cat is fearful of new things. You can remove the old litter box or leave it next to the Litter-Robot for a short time. Then, take a cup of litter from the old box and put it in the globe of the Litter-Robot. The scent will be familiar, and your cat should be inclined to check it out. Once your cat ventures inside and feels the litter under his paws, he’ll know what to do!
