The bathtub might not be the best idea. I would feed it a Sterilite tub with holes in it for air or a smalll critter keeer. It is much less stressful on the snake then putting them in the bathtub with all those smells. What about soap scum and cleaners? That is all really bad for the snake! I would advise against feeding in the bathtub. There usually isn't much of a mess, especially when you feed frozen/thawed mice. As for putting it back in it's tank, I wait about 10-15 min after I see them eat the entire mouse before picking them up and setting them back in their tank. Others might say different, but that has worked for us!
