hhw....I dont know the answers to your questions...Jeanne probably does, she is the resident rat person.

Monty joe is approximately 42 inches long. I had been feeding him multiple adult mice because that is all he ever ate before I got him and he is a finiky eater, well, at lest he was. I am still unable to get him to eat f/t but the f/k thing is working. Plus, i have allways had rat's for pets since the 60's, so it was hard to feed him a rat but finally got over that and did what was needed for Montys best interests.
