Why? Positive or negative feedback?
It is well documented that PETA has advocated killing animals rather than them "suffering" in shelters or captivity. The founder Ingrid Newkirk admits to euthanizing hundreds of animals in a shelter she worked in rather than "watch them suffer and be abused". The incident Buster references did happen and it follows a disturbing pattern for PETA.
From National Review Online: "in 2003, of the 2,224 dogs and cats PETA received for placement, only 312 (14 percent) ended up in homes. All but one of the remaining animals were killed. This has been a consistent pattern for years. The Center noted that between 1998 and 2003, PETA took in 13,021 animals. Of these, it killed 10,195, with 2,540 adopted and 261 transferred (their kill ratio has trended upwards since and is now over 90%).
In contrast, animal shelters located near PETA’s headquarters had a far superior adoption-to-kill ratio in 2003. According to the statistics compiled by the Center, the Norfolk SPCA found adoptive homes for 73 percent and Virginia Beach adopted out 66 percent, compared to PETA's meager 14 percent."

Before you dismiss the article as being "right wing" propaganda, these numbers have been officially documented with the Commonwealth of Virginia.
The people working at the SPCA shelters work their asses off on a shoe-string budget to keep as many of the animals alive as they can. It's too bad the PETA folks don't do the same. I guess it's easier for PETA to give these animals a shot than take care of them and try to find them homes. While PETA does some good, they are a radical organization that also supports the ALF and other "Animal rights" groups that engage in illegal activities. I would much rather support organizations like the ASPCA and Humane Society.
