I trained my ex-cat. I'd get up when I damned well felt like it.
My ex-girlfriend at the time, would get up to feed cats.
So he'd bug her on the mornings she was in, and snuggle up with me on the mornings she wasn't.
Same cat learned not to beg at the dinner table for food. Even when sushi was being served. And yes, he loved salmon. Begging resulted in treats -- of wasabi applied to the nose.
He learned after the 2nd time.
TL;DR: with a sufficiently trainable cat, this doesn't work.
Are you comparing the amount of attention cats need with the amount children need (particularly infants & toddlers)? You are so going to have a wakeup call one day :)
Ditto. I can't believe this isn't the top reply. Three and a half years post-fatherhood, I don't even remember what it feels like to sleep late. I've gotten better at managing bed times (lights out by 10:30-11 pretty much every night). And I wake up on my own by 6:30 even on mornings where my wife is handling the breakfasts.
All of which is just corroborating the linked post: just do it. Make yourself go to sleep at a reasonable hour. Make yourself wake up, by whatever means you want. You'll find you adapt surprisingly well.
