Kastty 15L Stainless Steel Dog Water Fountain for Multiple Pets, Quiet FS81

Kastty is an indoor dog water fountain for circulating drinking water, with a 15L (4-gallon) capacity and food-grade 304 stainless steel construction.

• Five-stage filtration — helps remove hair, food debris, dirt and odors from the water.
• Water for up to 10–15 days — reduces refill frequency for multiple pets.
• Room for multiple pets to drink at once — the spacious design is made for households with more than one pet, including large dogs.
• Viewing window and LED indicator — makes the water level easier to monitor.
• Quiet pump operating below 25 dB — circulates water without adding much noise to the home.

Keeping drinking water available for dogs and other pets can mean frequent refills, especially in a multi-pet home. Kastty combines a large reservoir with circulating, filtered water and visible level cues, so owners can see when a refill is needed. Its indoor design is suited to everyday hydration at home, including homes where several pets share a drinking station.

How does Kastty filter the water?

The fountain uses a five-stage filtration system to help keep circulating water cleaner and fresher. The filter combines a pre-filter sponge, two layers of PP cotton, activated carbon and a high-density sponge. Together, these stages are designed to remove common debris and odors from the water.

• The pre-filter sponge and PP cotton layers provide the system’s initial filtration stages.
• Activated carbon and high-density sponge complete the five-stage arrangement.
• The filtration is intended to capture hair, food debris and dirt while reducing odors.

How much water does it hold, and who can use it?

Kastty holds 15L (4 gallons) of water and is designed for large dogs as well as multiple pets. The spacious drinking area allows more than one pet to drink at the same time, helping avoid crowding around the fountain. Depending on use, the reservoir can provide water for up to 10–15 days, which means less frequent refilling.

• Made for households with one or more pets, including large dogs.
• The wide shared drinking area is designed to help pets drink without crowding or spilling.
• For indoor use as an everyday water station.

How can I monitor the water and pump?

A built-in viewing window and LED indicator show the water level. The light is blue when water is available and changes to red when the level is low, reminding you to refill; it can also help pets locate the fountain in a dark space. The pump circulates water continuously in a flowing stream designed to encourage pets to drink. Dry-burn protection stops the pump and flashes a red light if the motor is at risk of damage.

• The pump’s operating noise is below 25 dB.
• The visible window lets you check the water level directly.
• The low-water alert and dry-burn alert both use a red light.

The fountain’s food-grade 304 stainless steel is rust-proof, corrosion-resistant and easy to clean. Compared with plastic alternatives, the steel construction is intended to provide cooler, fresher water and help prevent chin acne. Pet owners seeking a shared indoor water source with filtration, visible water-level alerts and a large reservoir will get the most from Kastty. Its 15L capacity, multi-pet drinking area and circulating filtration make it suited to everyday hydration for homes with dogs and other pets.
