Nayeco Tray with Cococriba Sieve is a sophisticated tray for cat hygiene. It actually consists of a three-tray system. Thanks to this system you will not have the need to touch the feces even with a paddle, since they will fall to the bottom. It has a high and curved rim that will protect that the sand does not come out of the tray. You should place it in a secluded and ventilated place.
