This upgraded magnetic hamster water bottle holder is specially engineered for glass tank environments, offering a stronger and more stable magnetic grip compared to standard cage holders. The heavy-duty magnetic system ensures secure attachment even on smooth glass surfaces, preventing movement, tipping, or accidental spills. The included 2.7oz bottle provides clean and convenient hydration for small pets such as hamsters, gerbils, mice, rats, and other similar animals. The transparent design allows easy water level monitoring, while the adjustable mounting height supports pets at all life stages. ⚠️ Safety Notice: This product contains high-strength magnets. Please handle carefully. When attaching or removing, always slide the two magnetic components apart. Do not allow them to snap together or pull directly apart, as this may cause injury or finger pinching.
