After our new cat has managed regularly to miss their "normal" litter, we decided for this closed version. My concerns about whether our cat would ever go through the closed door, have evaporated in no time. On most incredible for me but the fact that the cats Loo smell that has otherwise been happy times dominated the hall, is completely gone! Therefore: buy recommendation. 1 star deduction's because of being too thin plastic shell. When take out the arresting me! Posted broken for the top shell. Since I have the topside but eh placed only normal and the lock therefore do not need, I keep the litter box anyway. Is probably due to the price.
