One of the things I liked about KC kittens was that you could carry them on your shoulder. When they turn into adults, you end up losing this option. Based on one of the hug options from the AIF pets, I think a shoulder drap option would be fun to have for adult cats, while keeping your hands free for anything else (and they won't be hanging on for dear life when you're doing active things, like dancing xD). While on your shoulder, they could look around curiously, lick their paw/shoulder, or lower their head if they fall asleep.
This would add two options to the interact menu, or just add back the shoulder option the kittens had (whichever would fit in the menu best):
Drape L & Drape R
Drape Left & Drape Right
Shoulder L & Shoulder R
Shoulder Left & Shoulder Right
I've attached a couple examples using my AIF Yorkie pair:
