I am seeing so many Americans post about upsetting the cat/dog/catdog by feeding them an hour later (because of DST).
(Maybe Europeans posted this stuff last weekend but I missed it.)
Have you considered just feeding the pet an hour earlier in winter time, and an hour later in summer time?
The cat doesn’t fucking care what the clock says, and it’s not like it makes your life harder. You can adjust, mate.
If you have an automated feeder, just… don’t change its clock.
