my snake has been eating mice its entire life(1.5 yrs.) all of a sudden, it has quit eating. its been 3 months now. he is still active, and looks healthy, though he was thicker.people have told me to go to frogs, but what kind? anyone know if its a specific frog, or any type? i have killed one by feeding it toads last year. i put three small toads about the size of a peanut each. she ate one and it killed her.
