A Tommo
A Tommo is a guy who owns a pigeon named Kevin and lets it roam free, even though it eats all his food and messes up his house.
Kevin the pigeon is a menace, and his master Tommo lets him do whatever he wants.
Tommo feeds Kevin all day, but Kevin doesn't seem to care about Tommo.
Kevin eats Tommo's breakfast, and Tommo just shrugs and eats cereal for lunch.
