According to the website PETA Kills Animals:
PETA’s “Animal Record” report for 2008 (PDF), filed with the Virginia Department of Agriculture and Consumer Services, shows that the animal rights group killed 95 percent of the dogs and cats in its care last year. During all of 2008, PETA found adoptive homes for just seven pets. Just seven animals — out of the 2,216 it took in. PETA just broke its own record. Why would an animal rights group secretly kill animals at its headquarters? PETA’s continued silence on the matter makes it hard to say for sure. But from a cost-saving standpoint, PETA’s hypocrisy isn’t difficult to understand: Killing adoptable cats and dogs – and storing the bodies in a walk-in freezer until they can be cremated – requires far less money and effort than caring for the pets until they are adopted. PETA has a $32 million annual budget. But instead of investing in the lives of the thousands of flesh and blood creatures in its care, the group spends millions on media campaigns telling Americans that eating meat, drinking milk, fishing, hunting, wearing leather shoes, and benefiting from medical research performed on lab rats are all “unethical.”
A couple of things. When this site says “killed”, they mean “euthanized.” And I don’t necessarily see anything wrong with storing dead animals in a freezer pending cremation. (What’s the alternative?) Otherwise, these numbers are horrifying.
