They are specifically designed for the Catit Design Senses, Flower, Senses 2.0, and Fresh & Clear Stainless Steel models, though you should steer clear if you own the Mini version. To get the best results and avoid carbon dust in your pet's bowl, make sure to soak them for ten minutes before the first use. Since they come in a sealed six-pack, you are set for several months of fresh hydration.
