1. After assembling and filling hooked the door. She strips off the bottom of Klos and hence can not vibrate.
2. The plastic is overall flexibility for dual Klappöffnung.Schiebt one on the wall, disfiguration plastic and the door can not be opened, a cat jumps on the cover disfiguration plastic and the door leaves the toilet to close no longer open, a cat jumps too quickly from the loo checked the lock and the door can not be opened. etc. The result is that the cats not ask for more in the toilet (or beyond if you're unlucky)
3. Place the carbon filter on the outside of the toilet may seem casual, the next morning the filter, however, was distributed in the apartment and in the top of the litter box is now a gaping hole unsightly. In addition, it smells.
To remedy this, I have added a strip of broken carbon filter in the upper rail of the cover (see photo), thus no longer drags the door on the bottom shell. On other issues, however, it changes nothing.
Overall, the idea of the double hinged lid in combination with a high bottom shell is still top, in this loo implementation is however flawed.
