Automatic Litterbox Central

I am a happy owner of 2 litter robots. The first one I bought is from 2004, I think. It has stopped working and has sat in my garage for about a year. I want to find out if there is a way to get this fixed. Are there people out there who enjoy trouble shooting/electrical engineering who may want this litter robot? I have a new LR and do not need this one anymore. I could give it away or have it repaired and then sell it. Any insight would be appreciated. Amity

I would absolutely love to have your old litter robot. I have four cats and two litter robots. A third would be absolutely great. I don't think I would have any problem tinkering with it until I got it working. Please tell me how to contact you and also to figure postage.
Thank you.
