I found a really clever way to water multiple cages, cheap and easy. I purchased the Zoo-Med Big dipper, I think it's called. Then I purchased a 5 gang air outlet ( for fish air tubing) I also bought 50' of air line tubing. I put the dripper high above the gang outlet. Ran a small piece of tube from dripper to gang outlet. Then I ran tube to each cage. The most I've tried is 5 at a time, but imagine you could do more. Sometimes there is a small drip from the gang outlet box, but it's worth it to me. My longest run to a cage is about 11' and the still drips perfect. Hope this new idea helps you...
