Petree Thick Waste Bag
The Petree Thick Waste Bags are worth the money as far as keeping the odor contained. I have 2 cats using the Petree Litter Box and when its time to replace the bag I removed the used one, tie it in a not and there isn't any odor. They are thicker than normal bags which prevents them from tearing and keeps the unwanted smell out. I highly recommend you use them.
These bags work well and can take a beating. Love the whole set up.
We love the easy clean up!
