I often wonder what takes place in my apartment when I’m not there. Today I came home to discover every rug crumpled, a pile of cat toys lined up on the welcome mat, candles on the bedspread, and baby kitty Grace herself sprawled, limbs akimbo, in the bathtub. Is Little Miss hitting the catnip too hard? Has she scored a dealer of her own? Do her pals enter via the fire escape and hold under-age, inter-species parties? Has she, G-d forbid, fallen in with the wrong crowd? Inquiring cat ladies want to know.
