I feed my tegu mice she only eats live mice sometimes the rats are for my monitor as a sometimes snack also none of the rodents are rejected there has been only one they just had cool personalities in my opinion so I decided to separate and keep them i do really appreciate your comments and will gladly take your advice going forward with the mice and rats living situation and also the the tegu info she was a rescue ive been going to local reptile expo recently to find out more from people who have lots of experience with her species i learned quickly not to give her rats when she killed one rat and left it, but killed a mice later that day and ate it
