How to support animal lover Betty White's favorite cause

When it came to people, Betty White loved to make them laugh. When it came to animals, she loved to lend them a helping hand.

A lifelong animal lover, White -- who died Friday at age 99 -- said her parents instilled in her a compassion for all creatures great and small. "They imbued in me the fact that, to me, there isn't an animal on the planet that I don't find fascinating and want to learn more about," she told Smithsonian Magazine.
