The Metcalf-Hatch Act forces tax supported pounds and shelters to turn over unwanted cats and dogs to New York laboratories. This creates difficulties for shelters/pounds. People who are aware of Metcalf-Hatch (MH) will tend to abandon animals rather than risk having them recycled into labs. And this places additional tax burdens on communities for rounding up abandoned strays. The cost of stray animals is already $400 million a year in the USA.
