i cant stand that there are no good water bottles out there.. remember the water buddy, great bottle, does not leak!! but they stopped making it years ago.. lixit does have one with the same type nozzle so it doesn't leak. it is plastic tho, so even tho it gets strapped on the outside of the cage, there is a chance your chin will chew it..[may dam girls do..ugh.. so i cover it with fleece].
i'm not saying you have to buy it from me, but just want to show you the bottle, i'm sure other places sell them too.. i love them. but they are expensive.
if you scroll down on this page, its the first water bottle.. the no drip
