PETA took in 2,216 animals last year, 7 found homes, the rest were put down. They apparently don't want to eat into their $32,000,000 advertising budget, so they don't really try to find homes.
I'd think that 2,216 PETA members would have been so choked up by the thought of killing the things that they could have each taken one home.
