well I don't have a king, I do have a milk snake! which is closly related. (I actually went in looking for a king and left with my milk!
Feeding wise: I have only had Sirius refuse food twice, when he was battling a small bout of scale rot..
after it cleared up though he went back to his hungry little self and hasn't turned a meal down since!
his feeding response is also very mellow, well sorta! I've notised as in the past two feedings of adult mice his strike has picked up some punch!! :laugh: but that's all it is, I have to shake the mouse to get him to actually coil around it.. and even then its one or two coils. Fun, but nothing like a king..
handling wise: my corns becoming more or a handfull to take out, like. toddler that's discovered he has hands! he grabs on to everything we walk by! lol and just wants to cruise around exploring.
I love him to death but now when he comes out I try to clear a room and let him just crawl around supervised.

he likes it, and I enjoy him not trying to go down my top every 5 seconds.
now for my milk.. He's a Mexican milk snake, which is a smaller subspecies. hell Max out at about 24 inches as a male, 30 for females.
Behavior wise: there soo much calmer then most milks!!
he's never musked me, he did poop fling at me the first 2 handling sessions we had, but not once
since! he did dart from me at first, and theirs no putting him down to explore (their fast!) but now he just sits there when I left his hide, hell maybe give a little hiss but once he's out, he's soo mellow!
like unbelievably calm, like spyderk said, he's kinda like a tiny ball python, just happy to sit in one hand and look around.. lol he's actually calmed down so much that really enjoy handling him now cause it seems like he enjoys it too!
now for feeding: aha.. I think kings have the craziest feeding responses!! my boys coiled his mice from day one! I got him at just over 3 weeks old and he was a crazy eater from day one!
he strikes like crazy, then throws 3 or 4 coils around it and squeezes the thing soo damn hard it looks like its gunna pop! :laugh: needless to say feeding time with a king snake is never boring....
