I buy these bags specifically for litter box cleanup. They're definitely sturdy enough for this, and I can tie them up and drop them in the trash,even in the kitchen, without worrying about the smell. They seem hard to come by, so I stock up when I see them.
I bought this ruffie bag because it claimed to help get rid of the bad odors from the garbages. It does get rid of the odors, unfortunately it is not as durable as the Ruffies extra strength wing ties. Whenever, we lift out the bag to take it out, liquids would drip onto the floor from the bag. This is because the liquids would fill up at the bottom two corners of the bag. Also, the bag is really wide so it does NOT fit nicely into our tall kitchen trash can. Unless you have dry garbages, I would not recommend buying this one due to the leaking.
