Sounds like the crash was just the cable box or whatever tipping over, not a real problem. Cats knock stuff down all the time, it's what they do. Five days on an $18 wrap seems fine to me, not sure why you'd jump to conduit for one bad night. Maybe just unplug the loose stuff before bed or move the stand so she can't get back there. Unless she's actually biting through live wires and getting hurt, this feels more annoying than serious.
