Can a BP cage be too big???

[Starscream]

I asked a friend if I can use a thermostat for multiple cages if they have the same temp requirements and he said he wouldn't suggest it. He says that's why they have rack systems.

The only time you can do this is if the cages are all exactly alike.

EDIT: Ack, really need to pay attention to if there is more than one page lmao. You're in good hands. And a thermostat is a must -- cheap ones are okay, but definitely try to save up for a more expensive and reliable one (Herpstats) down the line.
