I hate to preach about the ethics of venomoids, but i can't help it...unless you're using it for educational purposes where a "hot" snake wouldn't be safe, you shouldn't be keeping a venomoid...if you can't deal with keeping a venomous snake WITH it's venom, then you should find a different snake to keep (non-venomous)...chopping up snakes doesn't benefit anyone and if you're not confident enough to keep a mojave with it's venom then you shouldn't keep one at all...there is a lot of evidence to show that rattlersnakes and pitvipers in general do not deal with venomoid surgery as well as elapids do, so you might end up killing the poor thing....keep a copperhead if you think there is a chance you'll be bit, and stay away from the DEADLY mojave...as for cages, if you have to ask this question (how secure a cage do i need?) then you definately shouldn't be keeping a mojave, or any venomous for that matter.
