Hello! Since 2004 my ferrets haved used the 32oz Glass Lixit bottles - I have had to order a new Ferret Nation cage so I now need 3 more. The last time I ordered (2 years ago) they had the 3/8 nozzle. Now they just 5/16s and 7/16s in the 32oz size. Has anyone had experience with these to let me know which would be appropriate? I have no idea if these are good widths for ferrets or not. The people I am buying from were recommended by Lixit about 4 years ago since they are a distributor, but they are a store for birds. Thanks! Anna Marie [Posted in FML 6334]
