Haha, I knew he was in mid-stretch! That's the exact pose one of my cats gets when she stretches in front of the radiator. I got the radiator out today for the winter, and Christy figured out how warm it was almost right away. She does this thing where she sticks her front paws out and stretches, then she leans forward and stretches her back paws, and then she arches her back way up, with her tail in a loop. She also arches her back when you go to pet her, because she likes to have her back scratched and doesn't like to have her head touched. (Christy had to have ear drops for a while, and she absolutely hated them; it got to the point that I had to wrap her in a towel. Now she only lets me cuddle her head when she's quite relaxed. On the bright side, her ears have been great and her hearing is just fine. Wish I could tell her I wasn't just annoying her for fun, poor girl.)
I've just spent the last hour wrestling with kittens wrapped up in a towel so I can squirt eye drops into their eyes and up their noses to help them breath a little easier. I wish my powers of telepathy were stronger, I need a way to tell them "You've got the 'flu dear, and this is for your own good!"
