I have an 5 month old kitten she has chewed plug ends off of things that are plugged into electrical sockets
Double sided tape is awesome for kittens, they hate the stickiness. It's also great to put on your couches where they like to scratch.
get her something else for her to chew on!! this happend to me my kitten kept on chewign wires behind the tv so i bought her a scatch post and a few toys and she soon stoped chewign on tthe wires good luck hope i helped :D xx
If the other suggestions fail then go to the pet store and get some bitter apple or bitter orange. Apply it to anything you don't want the kitten to chew on.
Make a solution of 1 part tabasco sauce 1 part water, place in spray bottle. Unplug and spray any cords she is getting at. Let dry Replug The mixture will act as a deterrent when the kitten attempts to chew next
