Gizmo can’t get enough of sitting in chairs with people. If he can’t sit next to you in the chair, he’ll sit in the next chair.
Most of the time, now, we have to put a chair next to us for gizmo to hop into, otherwise he’ll whine and paw at you until you do either put him in your lap or put him in the chair next to you.
It’s totally weird, he’s gone from loving to be on the back of the sofa to loving being perched on chairs.
The key thing for Gizmo is being up high, I think. I think it has something to do with wanting to be closer to people or wanting to do what people do (sit in chairs). Either way, I see a Pinnochio story (The Pug who wanted to be a boy).
