At one point, I lived on a ranch with about ten horses boarded there. Someone asked, quite seriously, how we adapted the horses’ feeding schedules to the time changes. I couldn’t resist — I told that we just set their watches forward or back and let them get used to it. :=)
We used to have a cat who absolutely hated the autumn transition to winter (standard) time. Her stomach was on DST, and she did not want to wait an extra hour for dinner. Of course, she was delighted when we went from winter time to summer time.
