My cats were driving me crazy every time it was close to breakfast or dinner time, because they don't want to wait for breakfast or dinner... they want their food now.
And so a couple months ago I had Alexa set alarms for 7am and 6pm every day so that my cats would learn not to bother me until they heard it was time. And it totally works...
Problem is that I can't set Alexa alarms for anything else or my cats will get confused and think it's time to eat.
Something I learned the hard way when I was baking bread last week.
