‘If it’s cold, they stop mating’: New York City rat population may be on the decline

As a result of New York's most severe winter in years, the city may see a drop from it's estimated 3 million rats

Since arriving from Europe in the 1600s, New York City's rats have survived hurricanes, floods, terrorist attacks, riots, fires, a pandemic (they actually thrived during that), the Dutch and Crocodile Dundee II.

But as a result of New York's most severe winter in years, when the city saw snow, then a historic deep freeze, then even more snow, the rat population might now be about to decline. For a bit.
