Cats always find the coolest spot in the house or garden in the summer. In winter, they always find the warmest spot. If our cat, Milo, isn't curled up on someone's bed, he's always outside. In the hot summer months he sleeps under tall bamboo clumps in the side yard. In the cold, wet months he's just as likely to be outside. When I pull into the driveway at this time of year, he often hops up onto the hood of the car and sleeps there until the engine cools. Sleep is good anywhere the temperature is right.
