If they're dead already (either pk or f/t) I just put them both in and let the snake decide if they want to eat both.


If they are alive, then put ONE mouse in and see if the snake is interested. If it eats the first mouse with a strong response and then (after fully taking it in) starts looking for more food, drop the second one in. Again, watch carefully and make sure your snake is really interested in eating it. If after 15 mins or so it hasn't taken it, then remove it and house it until the next feeding.

That's what I would do.
