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