Yes the older ones can drink from it fine. I think they waste quite a bit tho. These learned to use it at 3 weeks old.Do they actually drink from that water bottle? I always assumed they would not figure it out. But if they can figure out vertical and horizontal "nipples" then I guess a hamster water bottle is not that different.
I was thinking of setting something up with nipples but I’ll have a problem in the winter with freezing water.
