The YNC Cat Dog Water Dispenser is a practical and reliable way to provide your pets with fresh water. Made of food grade PP material, it is stiff and odorless, so your pets will drink clean, healthy water. With a capacity of 1 gallon, it is perfect for use with cats, small dogs, or other small pets. The spring braking device on the barrel mouth controls the water level, so it wont spill over when your pet is drinking. The YNC Cat Dog Water Dispenser also features 4 nonslip mats under the base plate, which help keep the dispenser in place while your pet is drinking.
