i know her head looks too small for a mouse but snakes can take BIG prey items at times(not encouraging a huge meal lol) even for a 3 week old baby who is a lil underfed i think she can handle a small mouse or a rat pup oh and congrats on th new addition.

if you wanna see rat sizes go to www.rodentpro.com they show all the sizes for mice and rats.
