Jolly Bottec Leak-Proof Bottle comes with a leak-proof washer, spring spindle and steel ball. Top can be easily lifted up to refill the bottle with water. It also has a plastic belt to easily install it on wire pens or cages.
We recommend Jolly Bottec Bottle for rabbits and not for smaller pets, as the tube might be too large for them (i.e., guinea pigs).
Note: Since the top has a lift-up design, the top portion of the bottle is not spill-proof. Only the bottom part is leak-proof.
