Chicken Jerky is a cat treat introduced in Nintendogs + Cats. It can be found on walks on rare occasions. Although it is for cats, dogs can eat it too. It can be sold at Mr. Recycle for $4. Cats enjoy to eat chicken jerky, because it contains real chicken meat and herbs.
3DS: "Lightly seasoned with catnip, this is the ultimate snack for kittens."
