Look into the Rainmaker Mists systems offered by Ecologic. They are pretty top notch systems.

The most important part is the pump and nozzles. You can buy the rest at any hardware store. The nozzles are important to get the rate, I won't begin to guess what is best for you but there is information out there specific to to what you are housing.

The pump is also important, you want one that can run dry, as inevitably we all at some point forget to check the water. Also you want one that is self priming. It's also important to find a pump capable of supply all your nozzles. If you have 50 cages you don't want a pump designed for 4.

Best of Luck
