Ways to help animals outside of an animal shelter

So there are other ways you could help animals without being or helping at the animal shelter. If you ever think you can't you really could. For example if you see an animal hurt call some one or take it to a vet. Or if you see a homeless animal DON'T!! go and touch it right away. Because you don't know what there used to and you could get hurt by the animal. But if it seems friendly just show some love to it and attention.
