The Calico Critters Company makes delightful sets of animal families and play set-ups for children. You can choose from a variety of animal families, including mice, cats, bunnies, hedgehogs, pandas, yellow labs, elephants, and squirrels.
Besides the starter cottage illustrated below, you can find a variety of play sets, such as shops, schools, day cares, and park scenes. Furniture and accessories, too, are available to add to your animal homes. There are furniture sets for bedrooms, kitchens, living rooms, and bathrooms.
Calico Critters even have cars and a train for transporting your little creatures around their animal village.
These Calico Critter animal creatures have quite the imaginative world built up and ready to go. Of course, if you prefer, you can just get the family of critters and build your own imaginary world with recycled boxes and paper towel tubes. It's all up to you.
