These are tips from our website on getting your cat to use the Litter Robot. I'm including the link because the picture didn't print when I cut and pasted.

2. Getting your cat to use the Litter-Robot™:
In most cases cats will quickly adapt to a new litter box, however if your cat protests, here are some suggestions that may help:
To avoid unnecessarily frightening your cat, leave Litter-Robot unplugged until you are sure your cat is using it regularly. Clean cycles can be run by simply plugging in Litter-Robot.
Try enticing your cat into the globe with cat treats or cat nip. Hold the treat or nip through one of the waste ports allowing the cat to enter through the entry/exit opening. This will your cat become familiar with the interior of the globe. Note: This is not possible with the Kick’n Kitty guards installed.
If your cat protests by urinating somewhere outside of the litter box there is no reason to continue the 'cold turkey' approach. Bring back the old litter box, but leave the Litter-Robot out as well. By letting the old litter box get full it may motivate your cat to migrate to the cleaner litter in the Litter-Robot. You can also gradually move the old litter box closer to the Litter-Robot helping your cat get used to the presence of the Litter-Robot.
Cats love empty cardboard boxes. You can try covering the Litter-Robot with the cardboard box it came in. Cut an opening in the side of the box to match the entry/exit opening in the globe and cut a notch in the bottom for access to the drawer. Note: Leave the Litter-Robot unplugged while covered with the box. You can run a supervised clean cycle by simply plugging it in and waiting for it to finish and then unplug it again. Please refer to the picture below for cut-out ideas:
===============================================
What I'd add to the information on the website is that I would offer lavish praise (and maybe some cat nip or a treat) any time I found the reluctant cat exiting the box. I might even try putting the cat in the Robot and offering the reward when it leaves.
To get my cats to use the Robot (which didn't take much doing, I admit) I took a bowl of litter out of their old box and placed it on top of the clean litter in the Robot. They both went in within 5 minutes. Make sure you're using a compatible litter if you do this. Clay litter that doesn't say either "clumping" or "scoopable" is not compatible with the Robot and will leave a sticky, smelly mess!!
Less than 3% of cats don't acclimate to the Robot (we get this figure from our return rate) which means more than 97% do! While this is little consolation to the owners of the 3%, it gives you reason to not give up until the last minute. You have 30 days of in-home use to decide whether to keep the Robot or not, and we encourage you to keep trying for the whole trial period. Most cats will come around and use it!
