When they were very young, I was feeding them two appropriate sized mice sometimes every three days or so, and later as they grew, I gradually found them a nice happy medium that kept them at a very healthy weight. The female of course was busy getting beefed up for egg production, so she was fed two large mice, and the male usually got one, sometimes two, depending on the size of the mice, I always monitor what I think is appropriate at any given feeding, and depending how long it has been between feedings. I really don't feed all my stuff on an "EXACT" schedule, it varies a little quite often.
After the female laid her eggs, of course she was much thinner, but not too bad at all for just laying nine HUGE eggs her first time around.
She quickly gained her weight back by me feeding her a little extra for a while, and now she is right back up to a very nice healthy weight. You would never know she just had a big clutch of eggs not long ago.
The mice I usually feed my adult kings now are HUGE retired breeders, so they aren't whimpy little things by any means, and this seems to be just fine. Again, sometimes if they are regular sized adult mice, I will size them up to what I think is appropriate at that particular feeding.
I have MANY different types of snakes, and none are thin, or too fat, they are all just real nice and healthy. "
