I put my f/t in ziplock bags, so they are not soaking wet. I also will push all the aspen to the sides and clear out a little space in the tub for them to eat. I have had to pull aspen pieces from the mouths of a couple and I've had a couple mouth their prey so much they get all slimy and covered in aspen. I have actually washed off the rats, dried them and rewarmed with the hairdryer....
