Betty is right about that size (judging from top pic) and has been on small rats 3 weeks now - don't let that skinny neck fool you - they can take it down. When I went for the first feed i took the thawed rat down to her and looked at it and her and had serious reservations about her ability to clear it. Even halfway done the butt-end of the rat looked too huge for her to finish off but she did without a hitch.
