The matt came with my first littermaid, and i have used them since. it catches alot of the litter, but you can see the trail from the litter box to the kitchen a mile away by the sand trail.

Pros: Catches cat litter coming out of the box

Cons: Doesn't catch alot of litter

This really work to help control the spread of litter as cats exit the litter box

Pros: works to help contain litter

Cons: none

Works well. Cats paws sometimes get litter on them and this keeps it contined mostly on the carpet.
It doesn't slip on weooden floors.

Pros: traps most loose litter

Cons: none

This mat helps trap the pieces of litter from being spread throughout your house, also lightweight to shake off into the garbage. It also, allows you to take it outside and spray it off with the hose for easy clean up.

Pros: traps pieces of cat litter from being spread everywhere

Cons: none

It does seem to help keep the litter contained by cleaning it off my cats' paws. However, the corners keep curling up presenting a tripping hazard to humans.

Pros: Helps clean litter off cats' paws

Cons: Curling edges
