My cat used to do that awhile ago when she was a kitten also. I tried the bitter apple stuff and that did not work for my cat. I ended up wrapping most of my wires is split-loom tubing. What was weird with my cat she only ate the thin wires (Mostly AC Adapter output cables, I hated that I always had to splice them back together,Luckily no 110VAC cables) I guess she did not like 24VAC on her teeth though as that was the last cord I remember her chewing though (Alarm System) So wrap them in split-loom tubing it will prpbably be just a phase with your cat like it was with mine
