Although I haven't purchased them, I've recently noticed more than one supermarket chain selling packages of "Chicken Paws".
To me, they look exactly like chicken feet, though I've never purchased those either. The definition of "paw" generally refers to the foot of an animal with four feet, but I've never known a chicken to have more than two.
I thought perhaps it's just a marketing ploy to make chicken feet sound more cute and cuddly by calling them paws, but that could also be counterproductive towards encouraging people to eat them.
What is the difference between chicken paws and chicken feet? If there is no difference, why are chicken feet now being sold as chicken paws?
Well, live and learn! — As Sue's answer correctly points out, the United States Department of Agriculture does indeed make a distinction between chicken feet and chicken paws:
The chicken paw on the left does not have as much of the lower leg as the chicken foot on the right.
While the difference may seem subtle to many people, it's apparently very important to consumers in China:
Most premium jumbo paws are sold in wholesale markets and eventually make their way into high-end restaurants. Smaller paws, chicken wings, and wing tips, in addition to being sold at wholesale markets, end up at wet markets and processing plants, which use them in finished food products.
The market for chicken feet is more varied than that of premium chicken paws; larger chicken feet are sold to both wholesale and retail markets and are more commonly used for family consumption (and in barbecue stores), small feet are typically further cooked in processing plants. Chinese consumers in the Northwest and Northeast tend to favor chicken feet over chicken paws.
