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.

Training pad holder literally rises above the competition
Size: 24"X24"
We have been through a variety of potty pad products during our housetraining journey with our Havanese pup. The Petphabet training pad holder has been the best by far and has ended our search for a number of reasons: Pros: 1. Grid design keeps puppy from chewing/tearing/destroying/eating the potty pad. 2. Size is perfect for our pup even as he is getting bigger (15 lbs) - mileage may vary for larger pups/dogs. 3. HERE IS THE REASON THIS PAD HOLDER STANDS OUT AMONG THE COMPETITION - The top grid is elevated off the surface layer where the pad lays, which allows an air gap between the standing surface and the potty pad. This allows the urine to fall to the pad without pooling and without your pup stepping in it and tracking it everywhere! Cons/Areas for improvement: 1. We like blue but it's not for everyone! 2. The "posts" holding the mesh up from the base carry all of the weight of the dog and in some cases jumping or playing on the pad holder can cause the edges of the posts to cut through the potty pad liner, causing a (minor) leak. I would recommend the manufacturer design any subsequent models with larger, flat surfaces on the post supports. 3. The 4 piece design means the base is not solid but has a split down the middle that is not waterproof. This can be remedied by caulking the 2 sides of the base together with clear silicone assuming you will no longer need to disassemble the unit. 4. Poo can get caught in the grid if your pup has loose stool. If not removed quickly your pup may step on it and really pack it in there. After many trials with other products, we are very happy with this training pad holder and have bought a total of 3 units for different areas of our house. I highly recommend for small dogs/pups!
