Yep. Good luck. But consider that a lot of the money you make will be put back into new cages, feeders, supplies, etc. It might be hard to get enough even to pay for food for yourself, let alone housing and everything else. But if you are really serious and determined, I believe you could do it. It just takes a LOT of work.
