I was very happy to be able to simplify my cleaning the litter but these bags were a big disappointment to me: I have two "litter houses" which are quite large and these bags are much too small to be installed above, it is necessary really a classic little tray. But above paper is very fine, much finer than a solid plastic shopping bag which for me is the minimum to withstand the cats claws. They are even thinner than plastic supermarket bag, they look a bit like the plastic bags distributed at the vegetable department, to get an idea. Avoid it, and very expensive for what it is.
