There's no need.. Ball pythons miss meals all the time... Example
Got a Lemon blast back in March.. He was 450 grams great looking little guy..Never ate..didn't eat for 2 months...I didn't worry, why he didn't get to be 450 grams not eating, I waited and kept offering a rat every week, then after about 8 weeks he ate..not he pounds rats and just fine..
Healthy, subadult, snakes can go months without food and do it all the time, it's scary at first, frustrating after a time then it gets to be part of it.
