Yes...but then I feel guilty because some will come out and they're not eating that day (I need to space my feedings since I have so many snakes). Might sound silly but I always apologize to those who aren't eating that night since they're are all excited and I tell them they're going to eat soon lol
I've been feeding this way (blow dryer blowing at the front of tubs) from the get go and have always had a pretty good response (besides those who are in shed at the time or decided to stop eating with the seasons).
