DoubleSealing Design The water bottle uses a rubber gasket and a doublesealing construction to prevent leaks. This helps keep the hamster habitat dry, makes cleaning easier, and supports longterm use. Roller Ball Innovation A roller ball water regulation system provides even dispensing and mirrors hamsters' natural drinking behavior. An antibackflow function adds safety by reducing choking incidents during use. Versatile Cage Compatibility Engineered to work with uneven cages, the bottle base encourages hamsters to explore while offering a safe space for rest and retreat. Adaptive Hydration Support Designed for comfort with an ergonomic curved tip and a bodyadaptive structure. This creates a comfortable drinking angle and supports healthier hydration for small pets. Use scenarios 1) In a standard wire cage with multiple levels and uneven surfaces, the bottle remains stable and dispenses water smoothly as the hamster drinks. 2) In a large or irregular habitat, the base design accommodates uneven mounting and positions the bottle for easy access, while providing a cozy retreat area near the drink point. 3) In a busy cage where the hamster is active, the antibackflow and controlled dispensing help prevent spills and choking during rapid drinking.
