【Smart Heating Function】 Maintains water temperature at a stable 20-30°C even in winter or cold weather. It caters to your cat's natural drinking habits, reducing the burden on their body caused by cold water. The heater base and the main unit can be separated, allowing you to remove the base during warmer seasons and use it as a regular water dispenser. It helps your cat enjoy comfortable drinking water throughout the year. 【Water and Electricity Separation Design】 The rechargeable pump and heating base are completely separated. This physically isolates water and electricity, preventing leaks and electric shock risks from the source. 【Large Capacity & Long-Term Operation】 In addition to a 2.8L large-capacity tank, it has a built-in 5000mAh battery. It allows for wireless operation for up to approximately 45 days when fully charged, providing peace of mind during outings or power outages. 【3-Stage Filtration System】 The 3-layer structure of stainless steel pre-filter, water intake filter, and main filter thoroughly removes dust, hair, and impurities. It provides clean, fresh water. 【3-Mode Water Dispensing】 You can choose from 3 modes: sensor detection, eco, and continuous water dispensing. It caters to various situations, such as multiple cats, single cats, and cats that don't like to drink water. 【Low Noise & Silent Design】 It adopts a water flow guiding structure and a silent pump. The operating noise is kept below 25dB, maintaining a quiet environment even in the living room or bedroom. 【Easy Disassembly & Cleaning】 All parts can be easily disassembled. The large R-curve and smooth inner walls make it difficult for dirt to adhere, making weekly cleaning easy. However, the pump body and heater base are not washable. Please clean them by wiping with a damp cloth or a soft cloth. Note: For hygiene management, it is recommended to replace the filter every 2 weeks and the pump intake (nozzle) every month. The pump body is not washable, so maintain cleanliness by replacing the intake nozzle. The search code for replacement filters and pump intakes is B0FZ3JYXR.
