Dog for me, but yeah same. I wake up at between 6:30am and 7am after 3 years of my dog suddenly getting the urge to go out right around this time. It's so consistent in fact I've tried sleeping at 10:30pm, 12am, 2am - it doesn't matter. I am wide awake no later than 7am and usually have to take a nap mid-day.

My "one easy trick" is simply going to bed at 9pm and making it a habit

Just wanted to write exactly the same. Get a kid and you'll wake up consistently at 05:30

Had the same result with young dogs.

ha, mine wake up closer to 7a, so 5:30a is still “early”
