The Drinkwell Mini is the perfect fountain for small or medium dogs and cats. The Mini Fountain spouts 40 ounces of fresh, filtered water, giving a pet the option to drink from the flowing stream of water or the shallow bowl. The pet's drinking water is filtered through the activated charcoal filter, keeping water clean and fresh-tasting. The patented free-falling stream of water adds oxygen, which keeps water naturally cool and encourages pets to drink more. The narrow, compact design is easy to fit in any room and the fountain comes apart for easy cleaning.
