That's a clever idea. I'm always surprised at what a mess I make when there's no close by garbage can. And today I opened a big yellow bucket of Tidy Cat cat litter, (LOVE those buckets) and on opening the lid I pulled off a nice, strong piece of thick plastic that will make these things stay open. I had put it on top of the bucket till I'd have time to throw it away, but from now on it's a keeper.
Thanks for the idea.
