How does a double-layer mat catch litter?

The top layer has holes that let litter grains fall into a lower tray as the cat walks across it. You separate or lift the layers and pour the trapped litter back into the box.

Which size should I get?

Match the mat to your box and your cat's exit path. A 30x45 or 40x50 cm mat suits a single open box; 55x75 or 60x90 cm covers the floor around a large covered box or a multi-cat setup.

Yes, it is water-resistant and can be rinsed or wiped. Rinse and dry it fully before putting it back, and empty the bottom layer first so wet litter does not clump in the tray.

Most cats accept it because it lies flat and has no strong smell. Some cats dislike the hard honeycomb texture, so place it where the cat must step on it rather than forcing it.

Does it replace a litter box?

No. It is an accessory that sits under or in front of the box to reduce tracking. It does not contain litter or control odor on its own.

Is it good for kittens or senior cats?

It is fine for most kittens and seniors, but the raised texture can be awkward for very old or arthritic cats. A flat, low-profile mat may be easier for them.
