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.

It doesn’t stop leaks from the pee pad.
Size: X-Large: 28" x 34"
I’m trying to figure out how not to have leaks occasionally. I’m going to call the company to see if there’s something I should be doing.

Perfect for my dog
Color: Blue Puppy, Size: Medium Size 2
My dog (16 lb) LOVES to whip her toys around and throw them in the air to chase after them. This is the perfect toy for her to play outside by herself. I would repurchase for her over and over again if needed!
