These are the official replacement filters for Drinkwell fountains for animals. My cat is addicted to the fountain, and I do not tell you when the store where I bought it they seemed not even know that these filters exist, I say bravo major retailers that sell you the devices on which they know nothing, unable to provide the consumable! So I'm happy for having found here. I think the price is very reasonable and it is not the luxury they are in a lot of 3.
