The carolers and the canine went out to a sunny park where they sang "Come All Ye Faithful."
The public was invited to spread the holiday spirit with more than 400 animals, as CACC accepted donations of blankets, bones, treats and cat toys at its shelter at 28th and Western between noon and 3 p.m.
Donations can also be dropped off on Christmas Day between noon and 4 p.m.
Adoptions are also open during these hours and beyond. CACC is open for adoptions on Christmas Eve until 6 p.m.
