I have an idea to generate a lot of money with a pet shelter
So I thought about setting up a pet shelter with cameras and then have people pay online to feed them. I'd charge like $10 for a milk bone or something. $5 for a 1/4 cup of water. $100 gives them access to the yard all day. $30 for a toy or something. The walls would have slots that immediately open when a certain amount has been reached online so it'd be like instant gratification. If a pet is not popular it would starve but nobody would let that happen.
