Cats loaf by sitting with their paws and tail tucked under their body, resembling a loaf of bread. This behavior generally indicates that the cat is relaxed, comfortable, and feels safe. It can also serve to help conserve body heat by reducing exposed surface area, which aids in thermoregulation. Additionally, cats may loaf as a protective posture to shield their vital organs, especially if they feel slightly threatened or when in pain. However, loafing alone is typically a normal and content behavior, unless accompanied by signs of illness or distress. Overall, loafing is a sign that the cat is at ease and possibly conserving warmth while staying semi-alert.
