you should watch them decide the prey not worth constricting and just inhail the rodent.. My black rat she so greedy the mouse( small rat pup ) doed not even get it heart stopped and it down her throat. I have heard them still squeeling as she reset her jaws . I had to start giving her prey kill cause of her greed. My niece like to watch her eat them cause if the rodent kicks ( small rat pups ) the side of her body wit twitch and becky findsit funny ..
