If she is on mice, I would give her an adult mouse! When my ball was a hatchling, he wouldn't even look at a pinkie so I had to get a mouse with hair! I don't think she will have an interest in a pinkie! Wish you all the best! Where abouts are you in Ontario? There is a show on Feb. 28th in Mississauga! Here is the website if you are interested: http://www.reptileexpo.ca/mississauga/dates.html
