Responsibility.

Responsibility is cleaning up the poop from something you feed.

It cracks me up when people who don't have kids say, "I know it's nothing like having a kid, but I have to do a lot things for my dog, blah, blah, blah..."

I usually tune out after "I know it's nothing like having a kid..."

Because the rest of it - yeah, they're right, it's nothing like having a kid.
