How cute! Howard and Luna love the bathtub too...although more to play in and under (it's an old clawfoot one, so there's about 4-5 inches between the underside of the tub and the floor) than to sleep in. When it's hot, my two furry little darlings prefer to nap in the best spot in the house: Sprawled out on the bed, right in the path of the air conditioner.
