Better stressed a little than a burned belly right? I would wait 48 hrs. to handle after eating I handled one once at 24 hrs. because Brian at snake bytes said 24 was enough and had a partial regurge. Since then I wait 2 days or 48 hrs. Once your snake gets acclimated and had a few meals you could take it out after 48 hrs from feed and then use your own best judgement between once a day or every couple of days say 15 to 30 minutes of handling, you don't want to over handle them . I would leave it alone on feeding day and then the 48 hrs after. And then a little here and there between the 48 hrs and feed day. Not handling on feed day is not a rule but it is just using good judgement.
