I've even had a female go on feeding strike for six months and not lose any weight at all. You have _months_ before you need to worry, as long as it is a natural feeding strike, and not a disease. Which is unlikely. I would offer a smaller mouse, such as a hopper or even a large fuzzy, once every two or three weeks until he decides to resume eating. Corns will often break a feeding strike for a delicious treat like a rat pink, but before you do that, consider if you want your snake to switch to rats. This has only happened to me with one adult, but it's happened to me with several juveniles. I've converted a couple back, but a few persist in eating rats. I don't care- but if they aren't readily available, it's something you might want to consider. In fact, the above-mentioned female is a rat-only feeder, now. Every once in a while I can get her to take a peach fuzzy mouse, but nothing bigger than that.
