At the petstore, they had Ira on 2 pinkie mice every 5 days. When we first got him, he would strike at the first one, but refuse the second one. So, I would drop it in his feeder tank (I remove my snakes from their homes when I feed) and 5 mins later, he had ate it.
Now, he's a month older and is regularly striking at both. Last night he struck so violently that he actually pulled the pinkie out of the tongs, both times. Is it time to go up to 3 pinkies a meal? How do you know when to increase?
