A multi-purpose furniture structure and system may be used for caring for an animal throughout the life of the animal. For small animals such as puppies, this furniture system may be used as a dwelling in which the owner may train the animal to behave in a desired manner. Animal toys may be stored in the animal living space as well. A removable barrier such as a grate or plastic ventilated sheet may cover a front opening to prevent undesirable movement of the animal in and out of the furniture structure. Animals may use a detachable ramp member to climb to the top of the furniture structure. For larger or older animals, the furniture structure may serve as a bed or as a means to help the animal get into the bed of the owner. The furniture structure may form a bed for animals of all ages. The bed may be positioned adjacent an owner's bed.
