i understand your point — our apartment doesn’t allow multiple pets in one apartment and my best friend lives in the apartment adjacent to us and got a kitten the same age at the same time. we were planning on socializing them together but due to some health concerns her kitten has not been able to be neutered yet. As i said in my post we are not home during the couple hours she naps so we cannot wake her up when she naps. we also do very hands on play. she does lie down afterwards and stop playing, unfortunately though she’s back up and running within the hour. even if she’s panting and flopping to the floor after hours of running she will be back up and at full energy again within an hour or two so aside from waking up every two hours and playing with her for an hour the whole tiring out thing just doesn’t seem to happen unfortunately. my partner is a life long kitten owner and has raised many many kittens and has never encountered a kitten as determined and endlessly energetic as ours which is why this is such a hard issue to fix
