He means for rabbits and hampsters the drinking fixtures you buy have a ball in the part that they drink from. That prevents it from just leaking all over the cage. The rabbits suck on it and actually move the ball when they do to allow the water to be released. I never thought of that idea and i just threw 2 out. But around here they are more exp than the Little Dripper, like 8-9 dollars. If i were you i would add a small bit of hose to the end of it which will allow it to fall more gently on leaves where it might be easier for her to lap up. Thanks for sharing.
