Humans got an internal clock. My uncle who is a farmer has never used an alarm to wake him up. I personally stopped using an alarm years ago after high school, I just wake up ~5am and do my thing. The key is to just be consistent and your body will adapt.
Cats do too. My cat would wake me up if my alarm didn’t go off on time. Also he understood the difference between weekdays and weekends somehow because it didn’t happen on my days off.
