Bunny owners and small pet parents, these hanging water bottles are going to make your life so much easier! You get two complete 17oz (500ml) bottles that provide enough water for 1-2 days, which is perfect if you need to be away from home or just want to reduce daily refills. The siphon design uses gravity to automatically maintain the water level, and the sealed construction prevents leaks and keeps dust out - no more wet bedding or messy cages! What's really clever is the turnbuckle attachment system that works on both the inside AND outside of most cages, so you can position it at the perfect height for your pet to drink comfortably without straining their neck. The transparent PP plastic lets you check water levels at a glance, and the entire bottle disassembles easily for thorough cleaning. Compared to those noisy ball-bearing bottles, these are virtually silent when your pets drink - no more annoying clicking sounds all night long! Perfect for rabbits, guinea pigs, chinchillas, ferrets, hamsters, hedgehogs, and pretty much any small animal. Having two bottles means you can always have a clean one ready to swap out, or use one in the cage and another for travel. Seriously, if you're tired of messy water bowls or loud drinking bottles, this 2-pack is the solution you've been looking for!
