My cats used to spend much of their days home alone because of our family’s work schedules. I spent 40 or more hours a week at a job outside my home and had a 40-minute commute each way. My husband, a freelance photographer, was often on the road most of the day—and sometimes into the evening. While I was happy that they had each other for companionship while we were gone, I still worried about my kitties. Were they getting along? Were they getting into trouble? How were they spending those hours between 8 a.m. and 6 p.m. every day?
