This was taken a few years ago, but old habits die hard.

This cat has cleverly positioned itself to ensure that your neck is angled exactly right for optimum viewing through your magnifier.
Him and his sister are quite a bit older now and not quite so nimble since both of them were diagnosed with diabetes within a year of each other. Not through diet, just the genetic roll of the dice. Once we'd got them onto the right insulin dosage, they've been almost as good as new but sadly the time spent diagnosing the problem (mostly our fault for assuming it was just a diet related issue) has meant they're rather less sprightly than they once were. He's still a shoulder cat, but he needs help to get up there. Other than that, their behaviours are just the same, they just eat about twice as much... and what goes in inevitably must come out!
Edit: if you wonder how on earth you administer twice daily injections to a cat, it's a lot easier than I ever thought it would be. A light pinch to the scruff of their neck (where they were picked up as kitties) makes them docile long enough in order to administer the dose.
