This closed litter box is 50 cm relatively large with dimensions of 40 x 40 x. The plastic flap at the entrance, we have the same only once removed, so that our cat ever since dares enter. Surprisingly, it has however come to terms quickly with the new circumstances. Now that you just can not throw out through the entrance, the stray, the environment of the litter box will look more kindly.
The litter box has thus a vent with filter mat that we actually do not need the top of the basket, as the flap is so degraded. Otherwise upper and lower shells are held together with 2 plastic clips. The sticking pretty, but can be solved with little effort or close. Included will be a small shovel, which is sufficient in principle.
Conclusion: we can only agree with all the positive reviews here and recommend this cat litter box without hesitation.
Addendum: after about 6 months, the handle broke off suddenly, as I have to still pull off a star ...
