Just o.k.
The main problem I have with this litterbox is that my cat moves the litter around and does her business directly on the bottom of the box. When you roll it, some clumps stick to the bottom and the only way to get them off is to pound on the bottom of the box until the clumps come loose. I also purchased the litter mat that works with this box, and although there is litter on the mat, it's getting tracked through the entire room and that's quite gross. So I am not as impressed as I thought I would be. Also, this can be in no way a self cleaning litterbox. Something such as a Littermaid is way more self cleaning than this one. The regular Omega litterbox (RA15) is quite small and needs to be rolled and emptied every couple of days with one cat. With a Littermaid litterbox and only having one cat, I only needed to dump the receptacle once a week. After having owned a Littermaid for two years prior to buying this one, I think the Littermaid works better. I never used liners with my littermaid, I used plastic grocery bags with the receptacles. My only complaint with uncovered litterboxes is that litter still gets scattered outside of the box. I did go through one Littermaid Cabana and one Littermaid tent (both poorly made and neither didn't hold up). So I read the reviews on the Omega Paw and sold my Littermaid on ebay. I miss it dearly. This one creates more work than what other reviewers are saying.

Simple and effective, this one truly works!!
I've used about 6 different litter boxes over the past 5 years. I've tried almost every type: domed, automatic and even a toilet training system. This one is truly great. No mess, quick and simple to use (so you won't skip a day of cleaning because of the complexity) and my cat seems to like it. It is an economical and practical solution that I recommend to everyone who loves their cat!!

not perfect, but very good
A much cheaper alternative to a self-cleaning litter box. The Omega Paw is a great design and works very well for my small-medium sized cat. Here are some Pro's and Con's:

PROS:

* privacy for kitty
* seems to trap some of the smell (although that kind of clumping litter you use also greatly affects this)
* really easy to collect all the clumps, just by rolling over on its side, and then pulling out the collection tray
* nice size and design, firs good in a corner. good weight, cat doesn't move it around too much
* very easy to disassemble and clean - parts are small enough for this model to clean in your kitchen sink, I usually scrub it down once every few weeks. I haven't found any stains yet and it always cleans easily with some disinfectant followed by some soapy water and a good rinse

CONS:

* When rolling and collecting / refilling some litter will escape onto the floor, which is inevitable.
* fresh clumps (mostly urine) sometimes will not "roll" into the collection tray so occasionaly yuou will have to do a little scraping still
* Also depends on what little you use, but litter is tracked from the box outside quite easily, so get a tread mat for the front

overall, definitely a good buy!

Best cat box for the price
This is the next best thing to getting one of those $100+ models that is self-cleaning. All you have to do is turn this thing over on its side, then turn it back, pull out the tray with the dirty litter, and you're done! It's fantastic. This is great for those of us who don't like to dig around in a litter box searching for clumps. It takes 10 seconds to clean, literally. For $30, this is a great compromise between the $5 regular litter box and the very pricey mechanical models. Downside is that this box can seem small for a large cat. My cat still sticks her head out while she does her business but it works well for her. Overall, big thumbs up!

Love it!!
I absolutely love this litter box! I've owned traditional box type litter pans, I tried the automatic one that scoops after the cat leaves and deposits clumps in a bin(it was just okay), and now this. The Omega Paw self-cleaning litter box has made me re-think my decision to make this cat my last. I love my cat - I adopted him when friends couldn't move with him. He's been a great companion, but I hate cleaning litter boxes. The Omega Paw is so easy and stress free that I don't mind anymore! All you have to do is roll it on it's side, thump the bottom once or twice, then roll it back over and shake a little so the clean litter redistributes evenly across the bottom of the pan. The only drawback is its size - it's a little larger than the space a "normal" litter box might take... but totally worth it! Note, I have a 10 lb. cat and I think if he were any larger he might not fit in the "regular" size. If I get another, I'll probably buy a "large" so he has a little more room. I haven't had any problems with the clips yet, but I'm taking care to be extra-gentle with them based on other reviews here.
