I'm not vegan but I've probably done more to help animals than most average vegans.
I've donated a lot of money to REAL animal charities with actual scientists operating it, and not bullshit like PETA. Charities like The Wildlife Conservation Society, Animal Welfare Institute, World Wildlife Fund, International Fund for Animal Welfare.
When I was in high school, I volunteered at the wildlife conservation center at a local park, mostly just helping out with the loggerhead turtles.
I've helped out and taken care of horses at my family's ranch. I helped with a petition to shut down a local ranch that was known for mistreating horses.
I've also taken care of other people's pets, and helped friends who were rescuing animals. I love animals and nature, so I always try to do my part to help out. I currently have a family of deer in my woods who come across my property every evening to go to the lake. So I never built any fences around my house, and I leave out food for them sometimes (I know what they eat).
