This is probably true if you limit the consideration to animal suffering or weight animal suffering highly, but I'd like a bit more analysis of the effects of animal charities on humans. As someone who doesn't care about animal welfare very much, I worry about the effect animal charity outreach is having on peoples' nutrition and epistemics surrounding nutrition, which I see as both a high-leverage opportunity to do good and a high-leverage opportunity to do harm that the EA community hasn't adequately discussed.
