I changed all my water bottles over to glass a few years ago and have not had a problem at all with leaking water bottles! I got them from either "Ferret.com" or "Ferret Depot" the ferret store online sites. They came in two sizes. I will never use plastic again as I feel the glass is healthier for them also. Just my 2 cents worth. Eleanor, Donald and the weasels [Posted in FML 6504]
