Why does Dr Gary Michelson beg for donations for his foundation?

This has always puzzled me. Gary Michelson formed Found Animals Foundation to help animals. He states he funds this organization himself. Then why is he always begging for donations? His latest plea for money states if you give him money he will in turn give it to other nonprofits that help animals. Why wouldn't people want to donate directly to the other nonprofits? This makes no sense.

His plea, "You can make a difference for as little as $5. All items purchased through our Wish List will be donated to organizations working to keep pets safe and happy!"

Why wouldn't I want to just donate directly to the four groups myself. It makes no sense to go through another group.

He also says his goal is for a one shot sterilant. His has symposiums and charges people to attend them. Why is he always trying to make money?
