Protects floors
Size: X-Large: 28" x 34"
I love these pee pad holders. My dog goes near the edge of the pad and the urine gets on my hardwood floors. With these pads the edges of the pee pad holder catches the urine before it gets on the floors. It is very easy to clean the pad holder. I am so thankful it protects my floors!

Works well with the pads. Keeps them from getting bunched up all over the floor.
Size: Small: 24" x 24"
It was a nice idea, but my dogs chewed it up. If you don't have a chewer, then it's really nice.

Saved my sanity
Size: Small: 24" x 24"
I thought I knew everything about cats, but when my 14 year old cat stopped using the litter box, I could not fix it. I did persuade her to start using puppy pads but the problem was she would pee toward the edge and it always got on the floor. Or, defying everything I know about reality, she would find a way to pee UNDER the puppy pad.
I asked ChatGPT for advice and it recommended these. They fixed the problem by 80% and I'll take it! These mats help a ton. She still gets some pee on the floor, but it's not the huge problem it used to be. The edge on the mat keeps it contained. And enzymatic cleaner works its magic on the floor.
The clips that go on the edges are kinda fragile, but that's why they give you extras.
