Skin a Cat

Apparently, one side of a cat has more hair. The findings of the Swedish scientific establishment have been corroborated by a special enquiry by the BB Feline Federation. Many hair counts were taken of the side in question and consistently it was found to contain more hairs. The scientists determined that more hair was required on this side to insulate the cat from the elements while it was lying down. Perhaps you would like to examine a cat to confirm the findings. Before you do, can you guess which side of a cat has more hair?
