Whether I’m on the couch or at my desk, I usually have a cat in my lap. This benefits me in many ways. For one, I’m rarely cold. The normal feline temperature range is 100.4 to 102.5 degrees Fahrenheit, while the human body lingers around 98.6. Add a space heater to keep my feet toasty and I’m happy as a Florida retiree—even in the dead of winter.
