I bought these liners thinking that they would fit over the top of my cat's covered litter box, but the opening of the liner is too narrow. The only things I can use these for are trash disposal or recycling.
We've been using these liners for years and they are the best ones we've ever used. They fit our large litter box and are sturdy so they do not tear when the cat uses the box or when I change it.
I ran out of my usual brand of cat litter bags (the type that comes with its own string) so I thought I'd try these. I'll use them but I won't buy them again. They're too flimsy and rip easily, plus they don't completely fill the inside of the huge cat litter box I have. The only thing that is great about it, is that it does contain the litter, even if the bag is a bit small.
