A big, severe, plaid-hat-wearing dog insists that the small black cat in the red fez shouldn't be wearing a hat--any kind of hat--because hats are for dogs. His patronizing tirade doesn't convince this cat, however. Defiantly, she wears an assortment of hats, described in the gleeful rhyming text, and brings in other cats to join the protest. The silliness of both text and pictures offers a cheerful take on bossiness and managing conflict, with a win-win resolution.
