Whenever I get a shipment of f/t rats, the first thing I do is take them out of their packaging, weigh each one, and sort them into labeled ziplock bags, divided into 5 gram increments (35-40, 41-45, 46-50, etc). It occurred to me just today that I've never heard of anyone else doing this, I just do it because apparently I need to micromanage what my snakes are eating down to the gram lol. Am I the only one, or do other herp keepers do this too?
