Of course you're in the sun, you are a sun worshiper as most kitties. I am an open window kitty as I tried to take a few steps onto the patio earlier this year and just decided it's not for me. But then Lynn would be very scared I'd run too fast for her and get lost anyway. We have a bit of a cool down that is now here to stay the rest of summer and the windows are open airing out the humidity.
You just want some warmth in your bones...Lukas is the same way...
You appear to have a firm grip on that chair Poppy !
Whatever feels good, eh, Poppy? Especially on a sunny day.
