Convinced to 90%

Functionality convincing and work: The spreading (fine litter and wood-grained) falls through the holes on the lower mat. Approximately 90% are thus collected. The remaining 10% could only be intercepted if the mat even bigger and more around it would be, or there would be a pure, just so designed litter box room; o). After a few grains (especially the somewhat rougher wooden litter) still remain on the feet / in fur hang and fall only, preferably in my bed, or from the cats like to jump sideways over the mat away.

Material: for the cat OK, could be a bit softer, similar to the memory foam / foam. For all other hard plastic mats, most cats jump over anyway - so is virtually no restraining effect on the other.
Below could even more anti-slip material off / on it (as in the Car Trunk mats). The slips etc. on tiles namely like to get away / towards + her and you have to necessarily put something under the litter box. For large / heavy litter but that's no fun.

Priced completely covered.

In a square shape, it can be good kink and empty. A page should be closed so that when rumhantieren not yet falls out always something. When it rises to the foot or it is always clamped Unters loo, they can even be sucked.

Had the first Katzenkopf shaped mat and then got the manufacturer written, because I like a square, more could and got an immediate response. That's what I call service: o). This mat was then once set in Amazon and even the apparently comes from South Korea, it was there within a few days ...
