The Quick-Lock water bottle features a versatile lever style stainless steel no-drip valve that moves in any direction to release water, making it ideal for pets like chinchillas, ferrets, guinea pigs, and adult rats, though it's not suitable for birds or cats. Its Quick Fill top allows for easy refilling without removing the bottle from the cage; just flip open the lid and pour. Designed for both indoor and outdoor use, the bottle is made from UV-resistant, BPA-free plastic and includes a plastic clamp mount that attaches vertically or horizontally to cage wire.
