The charging cable for my Kindle Fire has been chewed in half.  Would someone please tell me which cable I need to charge my Kindle.  Does any place sell these besides Amazon.  I only have a Wal-mart, Kmart and OfficeMax in my area. My Kindle is dead so I need this soon please.
Thanks
P.S. 
Yes I know how and why it was chewed in half.  The 

 responsible has been banned from my bedroon!
