I'm enjoying this whole thread - we grow bananas and I made the mistake of letting a bunch ripen on the stem and then bringing the unripe remainders in the house - what a disaster. BUT about the guinea pigs dripping bottle ... we had that problem with our bunnies, and just got rid of the dripping bottle. Instead got them one of those bowls made for birds, with a clamp to attach to the side of their daytime enclosure so they couldn't knock it over. They now drink just like the wild bunnies and get a lot more water, which is overall good for them. And there's no mess.
