The cat had been showing up nearly daily. About mid-February I had to travel out of state. I made arrangements for someone to put out food for it. They never actually saw the cat and upon my return, I haven’t seen it since. The time we were away was the week when it stayed in single digit temperatures throughout the night. I had fixed up a box with a bedding and a light for warmth but it appeared to have been unused. Any advice? I’m really upset with myself that I didn’t do more to protect it from the environment.
