I have read up on a lot of peoples opinions on boaphile plastic cages. They seem to be really good and worth the money spent from what I hear. I am definately going to be getting a large PVC cage for my ball, but my question is what are your favorite PVC cages? I like the boaphiles because they come pre-assembled. Also is it ok to use heat pads underneath PVC cages? I plan to get into flexwatt and thermostat when i get more money but for the time being I have so new heat pads. Thanks for the input or even pointing out my possible ignorance on the situation.
