My two cats your cat litter always drag through the entire apartment. So I thought to myself time to buy a presenting for a litter box and came across this mat. First, one must say that it certainly gets here on the type of litter. My cat litter is relatively coarse and less fine. The subtle part of the litter remains good in the mat stick, but with coarse spreading the mat has no chance - everything is still further pushed and supported by the apartment. I have to look for a better alternative.
