I've just had some people ask me about rodent watering systems for some reason. I'm not sure why the sudden interest, but to save me answering everyone, here is the link to the place I bought mine from. Pretty expensive and not necessarily worth it for everyone, but they're the best and cheapest I know of. If you have less than about 20-50 rodent tubs, bottles are probably easiest. If you have more than that, automated watering may or may not suit you, but if you want to use it, I recommend this place.
