Should I up his food size or feed him 2

I was wondering if I should up my hypo brooks Kingsnakes food item size as I'm feeding him small rats every 5 days and it used to make him look fat for a couple days and the last 3 feedings seem like it's small for him and he can take something a little bigger or maybe a small rat and a weanling possible 2 small rats I'd pull him out for another pic but he seems hungry still and don't want to risk a bite http://images.tapatalk-cdn.com/15/07...5da73fad29.jpg
