question about non-profits

[stuntcat]

I have to quit a few memberships. I need to save money and want to switch to supporting a local farm sanctuary and a no-kill shelter in my neighborhood.
So these are my memberships:
-ASPCA
-Defenders of Wildlife
-Greenpeace
-Humane Society
-NWF (I knowwww, they support hunting. I've already been scolded for joining but I HAD to have that Habitat sign.)
-PETA
-WSPA

I want to drop at least 4 of them. I'm sure Greenpeace and PETA are bureaucratic giants who maybe I shouldn't have been giving my grocery money anyway.
Maybe I should ask which 2 or 3 would everyone think does the best with my donation money.
And maybe this should be a poll.

(And maybe this is a thread I shouldn't start? comparing these big places. will I get sued!?)
