Sure, Rodentpro has hairless large and extra large mice I believe. You really want to get a handle on the regurgitation so smaller meals is the better way to go. As far as the acidophilus is concerned you do need the one geared for reptiles and you can get that at Beautiful Dragon Rescue online store page. Another source would be Triple L Reptile or LLL REPTILE store page also. Reptile Basics may also carry the acidophilus. After a regurgitation , the intestinal tract loses some of the beneficial bacteria that aids in digestion and the acidophilus replaces it rather quickly. Beautiful Dragon Rescue would be my first choice to look. Hope this helps.
