(NBCNEWS) — U.S. government scientists bought hundreds of dogs and cats from “Asian meat markets” and conducted experiments that included feeding their remains to healthy lab cats for needless research, according to a disturbing watchdog report being released Tuesday.

Other experiments at the U.S. Department of Agriculture’s lab in Maryland included feeding dog remains to cats and injecting cat remains into mice, the report by the White Coat Waste Project found. The group is a non-profit that combats wasteful government spending on animal testing.
