The best type of cage your balls can have is a plastic pvc cage in my opinion. However any more then a few animals and you're gonna want a rack. Im not really a huge fan of racks unless you NEED to house a lot of animals in a small space. But everyone wants a million BPs, so a rack is probably your best bet.
I keep my balls in 4x2x1 Boaphile pvcs, but i dont breed and im not really planning on it
