This is a 3 pack of Cat It Filter Replacements for the Hagen Cat It Fresh and Clear Small Cat Water Fountain.
These Hagen Cat It water fountain filters are two stage water filters which supply clean, filtered water for your cat or other small pet. Each cat fountain filter is composed of two parts: an outer foam portion to collect debris, food, hair, fur, dirt, cat litter, sediment, and other large particles, while the inner activated carbon portion absorbs water impurities, filters chlorine, and improves the taste and odor of regular tap water. The specially designed Cat It water filter can also help to prevent recurrent kidney or urinary tract infections in your pets.
The Cat It fountain water filter needs to be changed about once a month for maximum effectiveness. This three pack of Hagen cat water fountain filters is also known by Hagen part number 50057.
