So something strange just happened, I thought I would share, see if anyone has any insights.
Wicket used to do a lot of kneading behavior, only with blankets, tshirts, and other soft things--we used to joke about it when we first got him, and how he had unresolved Mommy issues. He would always purr when he kneaded and his nose would get really wet and he would leave wet marks on our duvet every night.
After we got Atlas, he stopped doing it as much--probably partly because we don't let them both into the bedroom at night (the kitten is just too freaky right now, and never settles down in our room in particular) and because his routine was interrupted in general by the kitten and having to share all his stuff--we missed the kneading! He was less affectionate to us in general for a few weeks while he figured out his new roommate (and, I'm guessing, because he had less need of us from an emotional standpoint?). Now that they've bonded (it's been about a month?) and settled in together he's starting to get more cuddly with us in general--but has never ever been a lap cat and only recently began to let us pick him up and hold him, and only when he's in a very lovey mood. He likes to snuggle with my hubby way more than with me and will tolerate a little more picking up from him than from me.
Anyway, just 5 minutes ago, after a nice little dinner, he walked upstairs, walked straight up to my chaise (he has a habit of stretching out between my legs or along whichever one has the most room next to it) and let out this really loud MEOW!!!!!! and jumped right up onto my chest, all 15 lbs of him--OOF!--and started to purr like mad while kneading my chest and shoulder. 5 minutes later, he was done, jumped down, and went to have a bath on his chair.
?????? What was he thinking? I wanna know! The only thing I can think is that Atlas has this habit of jumping up on our laps and standing on his back legs, putting his front paws over our shoulders and sticking his head under our chins and snuggling like that, maybe Wicket is learning lap behavior from the kitten? He's never voluntarily gotten up on us like that, except the odd jump to a lap to get up somewhere higher.....
