NEW YORK — Cookie jars are a feel-good collectible that encourage smiles and waves of nostalgia. While some people start collecting with the cookie jar they remember from visits to grandma’s house, there are thousands of styles available. Animal-form cookie jars are undeniably a favorite. Whatever bird or beast suits your fancy almost certainly exists in cookie jar form. Kittens and puppies abound, but a startlingly wide range of choices is available, including frogs, squirrels, turtles, horses, foxes, birds, bears, goats, mice, pigs and kangaroos.
