This is why I don’t let Panda and Fernando free-roam my apartment yet. I have a tangle of cords and cables around my desktop computer that needs to be bunny-proofed before they can be allowed out of their X-pen (I almost had a heart attack one time when Fernando, on one of his breakout attempts from the X-pen, went close by my desktop PC area) as well as another power strip next to my bed. I need to shut down my PC soon to give the interior a good spray-out with compressed air (I bet hay and bunny fur is starting to get in there), so I’ll have to look at that time to see what needs to be done about moving or covering up those cords if possible.
This was a scary incident, but if your bunny is acting normal and doesn’t appear to have taken any visible injury (burns around the mouth, etc.), she probably didn’t get a shock (fingers crossed) since as jerseygirl says, she probably didn’t manage to bite through the inner plastic coating. Keep an eye on her and let us know if any of her behavior changes significantly.
