They are great but wish they came waterproof !!

Liner

The liner works well once it's waterproofed thoroughly with gorilla waterproofing spray. The seams aren't sealed enough if you don't, especially if you have a cat who aims for them. I bought it to make it easier to clean the box and have no downtime. It fits perfectly, which you would expect since it's from the original manufacturer.

I bought another liner because it takes a while for the liner to dry when cleaning. With two, I can switch them out and not have to worry about dry time. I have had no issued with purchasing accessory items or extra parts from Popur. I always get my purchases quickly, and I appreciate that.

The replacement liner came quickly and was very easy to change. The company is very helpful and easy to deal with.
