Japan's graying population has caused local governments to struggle to cope with the burgeoning problem of animal hoarding among seniors who are suffering from dementia or worsening chronic diseases.

According to officials, homes are becoming overrun with urine and feces from pet dogs and cats, making a case for central and local government officials to draft policies to address animal abuse and seek the advice of animal welfare specialists.

A 73-year-old housewife in Sendai began looking after five kittens following the devastating March 2011 earthquake and tsunami. She took five cats in that were born in the neighborhood after her husband, 79, started feeding them. Living off a pension, the couple could not afford to have the cats neutered, and their numbers increased to over a dozen within six months. As breeding continued, they came to care for even more cats.
