Andalus Brands Premium Cat Litter Mat Pack of 1-100% Waterproof with Non-Slip Backing of Litter Box Mat - Soft on Kitty Paws & Easy to Clean Cat Mats for Litter - Grey, Medium (23.5" X 15.75")

Really good at doing what it's supposed to - which is trapping litter tracked out of cat boxes. It traps a shocking amount of litter before needing to be shaken out/vacuumed. This is a much, MUCH better option than the envelope-style mats that are fastened shut at one end. The cats don't mind it, it grips the floor really well and doesn't slide, it's easy to clean, it looks great without being 'cutesy'. My one and only complaint is that the mat was shipped to me tightly folded, not rolled as it should have been - and even after using it for the last few months, the fold in the centre of the mat is still (annoyingly) visible and at this point, I can safely assume it's not going to go away so it detracts a bit aesthetically.

First mat with little nubs or bumps all over became my new boot mat. It was the perfect size 35 x 45 cm BUT Cat hated it. Poor thing waited all day to use her litter box until I finally caved and removed the mat.This one absolutely does a great job, no complaints from "you know who" BUT I wish it was 35 x 45 cm instead of 30 x 40 cm. My space is limited as you can see in the photo.

Nice and large, very good at trapping litter. Not so easy to clean but that’s because it’s so good at trapping litter. Also, non-slip when I step on it which is ideal.

My cats can toss litter into the next century! lol The larger size works like a charm

My dog is pee pad trained and we put the mat underneath his pee pad so if he misses the pad or it’s soaks through the pad it goes onto this Mat. Very cute with the paw prints not very absorbent though as the pee sometimes still leaks through the mat.
