Ba Boo is a 3 year old Shar Pei from Kodak, Tennessee.  Her family recently rescued a stray kitten and the dog and kitty instantly formed a bond. 

However, the bond goes well beyond just playing with each other.  Ba Boo, who has never had a litter, started to nurse Ally (the name given to the kitten).  At first, Ba Boo's owners just thought it was an kind, instinctive gesture, but before long, they noticed swelling and sure enough, Ba Boo was producing milk.
