We have 2 guinea pigs. I think I have bought 10 different water bottles, all of which claim to be leakproof and won't leak! They all do. I fill them up, put them high enough to not be pushed on by bedding but low enough for a comfortable height for the guinea pigs. Then I stand there and watch as it drips. By morning, a full water bottle will be empty and the bedding underneath soaked. Does anyone have experience with a water bottle for guinea pigs that won't leak (or tips for what I might be doing wrong)? I am so tired of wasting money on this. Thank you!
