The most obvious one being The Circe Order of the Dog blood, the group associated with The Process and Best Friends Animal Society. Rumored to take control of animal shelters, so as to sacrifice animals.

While digging I found another called Salem Saves Animals (yeah, that Salem). They aren't strictly a shelter, but they are associated with them. Their Facebook page is here: https://www.facebook.com/salemsavesanimals
Two of the five founders of Salem Saves Animals are explicitly named as witches on the open internet, while another has public artworks that seem pretty heavily influenced by esoterica.
Here is a story and picture of one of the founding witches: http://www.salemnews.com/local/x9838053 ... ness-rival
While the other (with picture, named as a Salem witch) has appeared on George Noory's show: http://www.coasttocoastam.com/photo/vie ... rama/65015
As per usual, this could be nothing (or it could be something).
Are there any other examples of these types of individuals running animal shelters or somewhat related to them?
Edit: Qualified the statement about SSA not being a shelter.
