“A little difficult to put together. Directions would have been nice. Not always convenient to have to go online for directions. The dome itself is good. It keeps my special needs cat from crawling out the back of the box and getting stuck behind the dryer. That was why I purchased it. I have tried other closed in litter boxes, but she wouldn’t use them. She has no problem with this dome. I would like to note, the kitty poo litter box is GREAT! I highly recommend it!!”
