Since I couldn't see it being mentioned already, forgive my blind eyes if I've missed it... but make sure that you give them something they CAN chew (willow products, weave-a-balls are especially popular with my two) so they can be distracted and hone their chewing entertainment needs on those items :wave:
Combination of this & blocking off/protecting wires is the best chance to avoid expensive mishaps, but it's not a guaranteed solution. Rabbits will be rabbits, and just repeating what has already been mentioned, if we leave something even remotely within our reach we only have ourselves to blame :lol:
