Or is this actually The Pixel Diaries? (Al)

Insignificant little thing, you'd think (fellow on the left of course . . .  we all know the chap on the right is pretty much running things around here these days).
And yet, combine with 40 plus temperatures with added humidity just for fun, a kitten in his major midday hunting frenzy, mix well and there's a well made recipe for disaster, or heat stroke at least.

So, the clue was when Pix charged out the catflap to hunt the swarm of crickets that were being all flittery and unresistable, and after a short while began panting like a very hot thing.  Now cats don't pant.  We know.  We googled it (at the time, after calling the vet about 'it is ok for them to ingest crickets, cockroaches, centipedes, large spiders, but before the panting started).  So.  Tempt kitten hunter king back in to the (relative) cool.  easier said than done.  Finally got him in, offered him bowl of cold water and cool tiles.  Cat cools.  Stops panting.  Drinks water.  Licks forearms (as roos do to cool down as they too don't sweat).  Then decides he wants to get back at the crickets.  REALLY wants to.  We locked the catflap, pulled the curtain, put basket in front on said catflap.  No go.  Cat pushes basket out of way. Gets behind curtain.  Begins headbutting catflap like small child having a tantrum.  So we cleverly (?) disguised catflap as piece of cardboard, which seemed to do the trick with the tantrum, but not with the sulk. 

 Which he kept up for most of the afternoon, interspersed with 'MOOOW' (not even a 'miaow', way more plaintive and irritated).  After some play in the later afternoon when it got cooler, primarily as a means of self-preservation on our part, to get the expression, below, resolved . . .

 He did finally calm down enough to 'help' me with my messing around in the sketchbook, trailing coloured pencil drawing of said beast.  Ironic really, that he was chewing the images of him that I was trying to draw.   But after a bit of chewing, he reverted to nice cat again, the one we collected from the shelter (as we remind him)

 

Of course we did get the last laugh (at him, as I don' think he joined in).  Later that evening, coming down the spiral staircase, I noticed young Mr P curled up on the lid of the laundry basket at the base of the stairs.  Very sweet.  On hearing me coming, he woke rather suddenly, moved rather ill advisedly (given the lid of said laundry basket was not on straight) and promptly flipped the lid like a flip top bit and deposited himself in the basket, with the lid back on top.  Really rather humiliating.  I wasnt fast enough (clearly a local problem) to capture the moment of him in the basket so just imagine a very embarrassed and really rather annoyed large kitten amidst the laundry below.,
