Looks like a 'parasitic twin', as these things are called. What a CUTE baby! I hope all goes well in her surgery!

MIRAMAR, FL (NBC) -- A Florida family is hoping surgery will save their six-legged kitten.

The kitten, named "Hex", was born six weeks ago. Veterinarians who have examined the kitten say that she will likely die if surgery isn't performed to remove the extra limbs.

Her owners are hoping the publicity will help them raise the funds needed for the operation.
