1. Introduction
Thank you for choosing the AONBOY Cat Water Fountain. This stainless steel pet fountain is designed to provide fresh, filtered, and flowing water, encouraging your pets to drink more and stay hydrated. Its innovative features, including a water level window, multi-filtration system, and quiet pump, ensure a convenient and healthy drinking experience for your beloved companions.
2. Product Features
2.1 Why Choose a Flowing Water Source?
Cats naturally prefer flowing water over stagnant water, which aligns with their instincts. The continuous circulation in this fountain keeps the water fresh and appealing, satisfying your cat's curiosity and encouraging consistent hydration.
2.2 "Big Eye" Water Level Window

Easily monitor the water level in the fountain through the transparent "Big Eye" window. This convenient feature eliminates the need to open the lid to check water levels, saving you time and ensuring your pet always has access to water.
2.3 SUS304 Healthy Food Grade Material
The pet water fountain is constructed from high-quality SUS304 stainless steel, imported from Germany. This material is resistant to high temperatures, corrosion, and oxidation, ensuring durability and safety. Unlike plastic alternatives, stainless steel helps prevent feline acne (black chin) in cats. (Note: The water level window is not stainless steel and should not be used in a sterilizer.)
2.4 108oz/3.2L Large Capacity

With a generous 3.2-liter (108oz) capacity, this fountain can provide sufficient drinking water for an adult cat for approximately 8 days. This is ideal for short trips, ensuring your pet has fresh water daily without constant refilling.
2.5 Multiple Filtration System

The fountain features a comprehensive multi-filtration system. It includes a high-density filter cotton, activated carbon coconut shell material, and ion exchange resin cartridges. Additionally, pre-filter sponges are located on the pump. These layers work together to intercept hair and fine debris, soften hard water, and filter out invisible particles, providing healthier water for your pet.
2.6 Silent Pump & Double Noise Reduction Design

The fountain incorporates a low-noise pump combined with a specially designed spherical structure to significantly reduce operational noise. This double noise reduction design ensures a quiet environment, allowing both you and your pet to enjoy undisturbed sleep.
2.7 Faucet Shape Design

Inspired by cats' natural attraction to running water from faucets, this fountain features a unique faucet shape. This design appeals to your cat's natural instincts, making drinking water more engaging and enjoyable.
2.8 360° Water Circulation

The fountain's design ensures 360-degree water circulation, keeping the water continuously moving and fresh. This constant movement prevents stagnation and encourages pets to drink more, promoting better hydration.
2.9 Pet Spine Friendly Design

The fountain's height and design are optimized to provide a comfortable drinking posture for pets, reducing strain on their spine and neck. This ergonomic design contributes to your pet's overall comfort and health.
2.10 Easy to Clean Design

The round, stainless steel construction of the fountain ensures there are no dead spaces for dirt or grime to accumulate, making cleaning simple and hygienic. The components are designed for easy disassembly and washing.

- Daily Checks: Check the water level daily and top up as needed.
- Weekly Cleaning (Fountain & Pump): Disassemble the fountain and clean all stainless steel parts with mild soap and water. Pay special attention to cleaning the pump every two weeks to prevent mineral buildup and ensure optimal performance. Use a small brush to clean the pump's impeller and housing.
- Filter Replacement: Replace the carbon filter every 2-4 weeks, depending on the number of pets and water quality. Replace the filter sponge as needed, typically every 2-4 weeks as well. Replacement filters can be found by searching for B0C73TR23R or B0C73XNDX3.
- Water Quality: Use filtered water to extend the life of the pump and filters.

- Unusual Noise: Noise can indicate low water level or a dirty pump. Refill water or clean the pump as described in the Maintenance section. Ensure the fountain is placed on a flat, stable surface.
- Water Leaks: Check all connections and ensure the lid is properly seated. Inspect the water level window for any cracks or damage.
