nope, we are talking live. Thankfully my BP is a garbage disposal and eats both no questions. though he will take a rat faster. the mouse he usual stalks longer, where the rat he eats it before it even hits the substrate.

I had no idea domesticated rats and mice were still prone too killing each other.

thanks guys and gals. I will store them separately. I only buy a couple at a time, so i thought maybe i could swing it.
