so i wake up this morning to our normal routine, and about a half hour later i realize that madison has been really quiet

and i havent seen her around. so i go into the bedroom and find her happily chomping away at my cell phone charger

...which is in multiple pieces (and still plugged in). i dont know how she didnt electrocute herself

, but this is the 3rd cord she's chewed through in the past few months (2 laptop chargers...not cheap).
She had seemed to stop for a while and not chew on any cords, but now shes back in the habit. Any suggestions for how to make her stop/learn that it's not okay. Of course i disciplined her as soon as i caught her in the act...but is there a preventative measure? I definitely try not to leave cords on the ground, but she sure is sneaky

!
