Leo the Cat lives with Evan McNulty, Software Test Pilot, who writes:

He is a dapper cat. He is also a good cat. He is named after Leo McGarry, my favorite character from The West Wing.

Leo, we should tell you, is well-known — at all points of the compass and in the lands and seas in between — as a Very Good Kitty.

Plus he looks way sharp in that hat!
