Bests & Worsts Reviews from Amazon

Looked good when first arrived. Thought sides were high enough to hold litter in. I received it March 29, Its now 5/1 and I just reordered prior box that I had. I just cleaned out box, and for first time in 2 years with my furbaby, the smell made me gag. I clean box out daily, replace about every month, and never had issues with kitty litter that I use. Only difference is the box. 1) kitty litter is still getting out to back and sides, so high sides make no difference, really. 2) that liner trapped urine btwn liner and box. I ended up getting rid of liner. Even after I cleaned it, smell lingered. 3) odors are absorbed INTO the plastic. No matter how many times I wash box out, some odor still lingers. 4) corners have these little tube things that run up them. Makes cleaning corners insanely difficult. 5) the cover top - if you have a large cat, he has to pee crouched, which is very awkward for my cat. The cover does not allow for large cat to lift his head. NOT A JUMBO BOX BY ANY MEANS. Like I said, going back to corner version of my old box, this time with a cover. I can't change this out fast enough.
