It's essentially an old store that Banksy has converted into a pet store themed art gallery.
If you're in the New York area, you can see the gallery at No. 89, Seventh Avenue South, Greenwich Village, New York (Open 10am - 12am Daily until 31st October 2008)
If, like me, you're nowhere near Greenwich Village, and aren't likely to be anytime soon, take a look at the website by clicking here.
