Food Grade Material: Our leak-free cat water bottle is made of high-quality plastic, non-toxic, BPA-free, safe and durable. Sealed design prevents water leakage and dust from entering. Our bowls are made of environmentally friendly thickened plastic, smooth and odor-free, safe and stable. Compared to traditional water bottles and bowls, our set provides a more comfortable and hygienic experience for your pet. A must-have for busy pet keepers: If you travel frequently and worry about your small pets not having enough water, this 18x8.6x20cm, 500ml capacity water bottle is a must-have for you. It ensures your pet stays hydrated while you're away without cluttering the cage. Use inside and outside the cage: You can install it outside or inside the cage according to your needs. If your pet is naughty, it is recommended to install it outside the cage. You can easily turn the water feeder on or off for cleaning and water refilling. Dust-proof and leak-proof: The sealed design prevents water leakage and dust from entering. Compared with a large water bowl, the water is less likely to be contaminated, and it will not cause oral inflammation due to long-term contact of the chin with water. Make your baby more comfortable: Compared with traditional water bottles and bowls, our hanging water fountain provides your pet with a more comfortable and hygienic drinking experience. By fixing it at the correct height of the cage, they won't have to lift their necks.
