Yes, Farm Sanctuary is great for Adopt-a-Turkey. The turkeys there get to have a (bird-friendly) Thanksgiving dinner! I am going to adopt one this year so I'll have something kind to think about when I'm at family events full of dead animals.
Or, you could just donate money to any good organization, like
Mercy for Animals,
Defenders of Wildlife, or just do a search for a highly rated organization on
Charity Navigator.
