I've been useing these Water Silo's. I had 5 of them for multiple water stations. But I find they either slowly leak/drip - or, not sure how, it just completly dumps out!

So I can fill them all, and a few hours later, there's a mess on the bottom of the cage and no water.
I've tried this water bottle, but they didn't figure out how to use it....
And this one... And these ones....
I'm frustrated, and tired of spending money for it to leak.
