Innovation: Water regulation technology with rotation provides even water distribution, mimics natural drinking behavior, and includes anti-backflow measures to reduce accidents. Robust bottle: Made from safe, wear-resistant food-grade materials, offering a durable solution to maintain a hygienic drinking environment without degradation. Universal compatibility: Designed for irregular cages, it promotes hamster exploration and provides a safe space for rest and protection during activities. Dry cage design: The dual-structure with a rubber gasket protects the cage environment from moisture and supports hygiene with minimal effort. Use scenarios - Daily cage routine in irregular or multi-level habitats: ensures reliable hydration as the hamster moves around. - Play and exploration: anti-backflow and secure mounting prevent spills during activity. - Cage cleaning or transport: moisture control helps maintain hygiene with minimal effort.
