Hmm, having some ASF's myself, it doesn't seem bad at all, if you are going to keep this animal as a breeder for the forseable future and you had ASF's this wouldn't be a problem, but if you planned on moving it down the road, then I see what you mean. Chances are you could send the rats/mice with ASF's bedding (if you had access to that) and the snake would take them (Just a little trick I learned from a mister Freaky Frog!).
