To say having the flu is a miserable experience is putting it mildly. I should know. I just spent the week after Christmas incapacitated on my couch, too tired and achy to remain in an upright position for more than ten minutes at a time. Throughout the ordeal, my three cats remained by my side. Or, more accurately, they remained curled up by my head, draped across my legs or snuggled into the crook of my arm.
