We usually wait a day or so. The snakes just aren't quite interested in being handled right after they eat and I know how I feel after a big dinner so it just seems nicer to let them get in a warm spot to digest, let them take a nice cool drink from their water bowl and just chill out in a safe zone. Plus, we feed at night and usually after feeding I go home and we then go to bed. The next day or so we'll decide to go pick one of them up again
