I have never used IRIS brand pet products, and was so excited to try their top entry cat litter box. I am a long term cat owner, and one of the things I despise is when they shoot litter all over the place. The litter box isn’t too big, it fits perfectly into the corner of my bathroom. It’s easy to fill and looks attractive as far as a litter box goes. :)   It is very easy to scoop and keep clean, and the top entry prevents the majority of the litter from being all over my floor. I love this product and highly recommend it! Compared to a standard litter box, this far exceeds the convenience and cleanliness!
