2.5L capacity and automated design make this pet fountain ideal for up to 35 days of use. Creative design is ideal for cats, dogs, and other pet sizes, eliminating frequent water replenishment. Crafted with environment-friendly, BPA-free materials with food-grade certification, this fountain ensures safe use. A super silent, 2W pump runs up to 10,000 hours and allows for up to one week of use without refill. Three different water flow settings—waterfall, bubble, gentle fountain—maximize oxygen contact for pet health. Easy filter replacements occur 1-2 weeks in summer and 2-4 weeks in winter; monthly pump cleanings are also recommended.
