It was an enjoyable day for seniors at Enomoto Clinic in Tokyo's Toshima Ward when Japanese Animal Hospital Association volunteers visited at the end of January for the Companion Animal Partnership Program, commonly known as animal therapy.

About eight volunteers with four dogs and two cats were welcomed by the members of the clinic's "silver floor." The volunteers provided recreational activities for the seniors as part of the program.
