Heck no to PETA! I have some negative feelings towards that "charity." When I get involved with any organization, I dig really, really deep and want to know a lot about what exactly they're doing to make a difference, where the money's going, etc. I do not like PETA. I used to, until I learned a lot abotu them. For one, they promote sex and nudity, not animal welfare. Mostly anways.
I don't know a whole lot about the other foundations you've listed, but I do support the 700 club, Action Against Hunger, ASPCA, Alley Cat Allies and Alley Cat Rescue. Those are proven legit and are truly amazing. Most of them, they allow you to see and know exactly what they're doing, where your money is going, etc.
