I've noticed a few posts here and there on keeping a separate cage for feeding. What are the advantages of doing this? Also, wouldn't you need to move your snake back to its normal cage afterwards, or do you leave it in the feeding cage?

I'm currently using a 20 gallon tank with screen lid, but the natural humidity and the temperature with the heatpad are sufficient for it to not be a problem, but I bought 2 sterilite containers yesterday anyway because they were 50% off and I'm sure I'll make good use of them in the future.
