Purchased for my cat, I put in some used litter to help it get used to the scent, but my cat didn't like the dome shape and didn't use it. I left the used litter in for about a month to see if it would use it, so there's more odor than expected. Because the litter was fine-grained, I couldn't remove all of it. The unit functions without any problems. Please purchase only if you understand that this is a used item.
