This is timely. Out of my five cats, my primary boy has been really needy or making a game out of hop on table, walk on keyboards, get picked up, scritched and tossed down. Repeat. Even cat tv on youtube hasn't been helping.
Just be glad the "secondary" cats haven't decided to vent their frustration.
My ginger passed and I adopted a cat who was named "Tank" because he was a little box of a pre 4week cat. Got him at 5-6 weeks, his name is Tiny Jerk because even at a young age - tooth brush, toilet paper, socks got carried off.
It was a bond. So while primary and secondary are not the best terms "my cat" and the others isn't either.
He is a great cat, he's also dealing with moving from the place he was raised to a new home (mover ~1yr ago, but moved him up - and the rest - 6mo ago). He gets all the attention he demands, but it's hard with the typing.
