We've had my cat Roto-Borola (pictured here) for over two years, we got him when he was maybe five months. A couple months back I discovered he really enjoys having his head massaged. He likes me to put a good bit more pressure on his head than I would expect him to be comfortable with.
He's still a very playful cat at times, and I try to engage with that as best I can but I don't always love being play-bitten. At some point a while back, if I'm petting his head and move my hand somewhere else near him, including petting his back or somewhere else on him, it sets off a timer of 15-20 seconds typically (usually around 10-15 seconds with no reaction, when he opens his mouth just a hint it means he is about five seconds away) for him to play bite me. If he's laying on top of me the timer it sets off is just for exiting the ride. I've been playing with him pretty rough by squeezing his head or giving him a little noogie, but it just hit me that this has really been him training me in how he wants to be pet.
So I'll give him a pretty rough noogie and he acts like "oh no, I'm really trying to bite you but I can't when your hand is right there", but he's definitely able to outspeed me. And I'm realizing now in retrospect, I started going for the back of his head because he left me one spot to find where he would pretend that he can't get to me. And he gradually trained me I needed to be more and more violent if I wanted to not get bitten.
So yeah, I put my entire hand around his skull and squeeze a bit tight and somehow he loves this. Realized a few months ago that this is his thing, realized today that this is something he taught me.
When my boy was a kitten we did showertime together for probably eight months. The day he grew up was heartbreaking for me, but I look back on the experience with fondness now.
We had a transparent inner curtain to our shower and he liked to stand on the tub edge between the two curtains while I would shower and watch the water come down. For a little he'd quickly come whenever I was opening the bathroom door, but after some time he figured out that not all bathroom visits are showers.
If he was somewhere else in the apartment when I turned the water on, he would absolutely bolt in, and scream while he was sprinting. Like he was upset I had started while he was in another room. It was really heartwarming for me, it was so cute and his enthusiasm was infectious.
After six or seven months he started growing up and began gradually treating showertime less like recreation and more like an obligation. Started occasionally arriving late and cranky from being woken by me turning on the faucet.
And then one day he didn't come. I knew I'd see that day eventually but it kind of hurt at the time. All in all though, those six months of showertime being his favorite part of the day are memories I really treasure.
