We have advanced from just feeding the cats (which I am sure belong to someone in the neighborhood) to leaving the garage door open about a foot so they can come inside. An old store bought quilt was brought in off the back porch for a soft bed after he found a kitten curled up on a cold lawn mower.
He mentioned a heater he had bought. I don't even remember it but it's electric. As I type, it is plugged into the garage outlet to warm up a garage that has the door open a foot. Present temperature: thirty-one degrees and light snow.
And to think it's sixty-three in Jersey.
