My brother is an engineer and has designed a cat litter box that is superior to all others. He's serious about this thing and I think you could see it someday soon on store shelves. He set up a survey hoping to gather information that will help him tweak his finish product if necessary. If you own a cat, would you mind taking the survey to help him out? I'd appreciate it very much!
