The connection between catnap, dogday, and comic is rather loose. Maybe in a comic, there could be a scene of a person having a catnap on a hot dogday, but that's just one possible way they could be linked.
There might not be a direct relationship. A catnap is a short sleep, dogday refers to hot and lazy summer days, and a comic is a form of entertainment. But they could potentially be combined in a creative story or theme.
Well, catnap and dogday have nothing to do with comic directly. But you could imagine a comic where a character takes a catnap on a dogday and funny things happen.
