This morning it was -18 C when I fed the East Side Gang about 9:30 - I have a thermometer there. I stopped again about 12:30 to give them fresh water and more food if they were interested and they both came out to eat. Because the sun was beating down on the cat's area it was a little more tolerable. In the more open exposed areas it will be much colder.
Spirit was snoozing in one of the sun shelters, came out to eat then climbed back inside the sun shelter. He will be nice and toasty while the sun shines.
