Johnny Town-Mouse was born in a cupboard, and Timmie Willie was born in a garden—this according to Beatrix Potter, who modeled both of her hantavirus-carrying protagonists after people of her acquaintance. Transposed to the city, Timmie Willie was chased by a maid and a housecat, while Johnny Town-Mouse's visit to the countryside was spoiled by cows, lawn mowers, and boredom. Both characters enjoyed good mental and physical health only in the settings to which they were accustomed, although Potter made it clear that her far greater sympathies lay with Timmie Willie.
