I like this litter box. I've had so many different types of boxes and "systems" and now I'm back to the basic no frills litter box. Its a nice size; all my cats fit nicely and I have some big boys and girls! It seems a littler larger to me than the average "large" litter box, but I've never considered the large size of most litter boxes really that large (is it just me?) The inside is very smooth and with the clumping pine litter I use, nothing sticks to the bottom when scooping (which is one of my pet peeves!) You can't beat the price. Happy with my purchase.
