Below is my lengthy review of the Omega Paws Roll N Clean Litter Box which I posted at Petco.com.
If you go to www.Petco.com and search for this litter box, then sort the reviews by "Most Helpful", you will find this review listed first.  Because many people have had a few difficulties with this awesome litter box, I decided to address those concerns and offer advice on how to increase the usability and success with these "tips and tricks."  I hope these tips can also help my own kitten buyers who decide to give this litter box a try.
