Best Litterbox Ever
This is absolutely the best litter box I have ever had, and I've used everything from your standard box and scoop to an electronic one with a motion sensor that cleans automatically! This is easy to use, works perfectly, and has made cleaning the litter box less of a chore. My cat likes it too, because I now clean it more often!

My 7 year old can operate this easily
I got this as a gift last Christmas from my children, after much prodding by me to the spouse. We had decided a kitten was right for the family and as usual I somehow ended up being in charge of the messiest part - litter clean up! Assembly is easy and quick. I agree the closing clips are a bit flimsy looking and at first I was suspicious that it would actually keep the litter in the box when rolled. My biggest complaint with the standard litter box was the kitten was kicking litter out all over the place and I was tired of having to clean the box AND the floor all around. The Omega was the answer to my prayers! The litter not only stayed in the box, but cleaning it out of the box was as simple as a roll to the right and emptying the collection trough. Unless you are aggressively rolling the box around or the offspring decide to use it as a step stool, I've found the clips hold well and they do indeed keep the litter in the box while rolling.

A year later this box is still doing it's job and we now have a full grown cat and another kitten both using it with no problems. Occasionally the clumps stick on the bottom, but as my 7 year old pointed out to me the other day, you just give it a thump and they come right off. Maybe I have weird cats, but even in a traditional litter box they dig down to the bottom to do their business and then I have to dig it out of the box. I'd much rather thump on the bottom of this box then have to dig out the mess on another box.

In the last month I decided that my 7 year old could manage the litter box as part of his chore list and he's doing brilliantly! I don't have to worry about his hands coming in contact with the mess and he seems to think it's fun to empty the box. Win-Win!

Prrrrrrrr!
The concept is good but when the litter starts to come out from all over, it is a mess!! Both sides do not stay together longer, the weight of the litter and excrement wears off the locks.
It lasted one week!

Is it wrong to fall in love with a cat box?
This box is amazing! For the average sized cat I definitely recommend getting the large box. The box was easy to put together and easy to clean, just roll all the way over, roll back, level the litter, and pull out the tray. It is absolutely amazing. Been using it for about 1 month now and no issues. Thanks so whoever invented this marvelous product!!

Nice
I like the way this litter box looks and works. It is a bit too small for my average size adult female cat. She isn't comfortable using it but she does try. I put a disposable pad in front of the entry and she pees there but goes inside for bm's. Perhaps she's too old to figure it out. Also it's a bit too expensive but happily made in Canada.
