Tons! What kinds of groups were you most interested in? General animal groups? Rescues? Wildlife? Feel free to send me a message and I'll be more than happy to help. I screen groups to be included in the Etsy for Animals Charity of the Month program, so I've done a lot of digging and verifying of dozens of animal groups' programs. :)
Off hand, here are a few of my personal favorites:
Carolina Pet Rescue (I foster rats for them!)
Mercy for Animals
Compassion Over Killing
Alley Cat Allies
Operation Catnip
United Poultry Concerns
and many more. Just put their names into a search engine and you should be able to see their websites. They do great work!
