Crack-Addicted Squirrels?

I ran into this article concering Pete Doherty of Babyshambles (formerly of The Libertines) making his kitten smoke crack and saw this quote:

DOHERTY’S kitten is not the first animal with addiction problems. In 2005 The Sun told how squirrels in Brixton, South London, became hooked on crack cocaine hidden by addicts in gardens. Residents said the tufties had bloodshot eyes and were “digging desperately” in flower-beds. In the US, crack squirrels are a recognised problem in New York and Washington DC parks.

Explains a lot.
