well my bp ate his second rat today but he had a pretty hard time getting its front legs in his mouth. it took him about 15 mins to swallow it.when the rat got to his belly his scales werent spread apart but he definetly fatter.his neck is really skinny and it was red while swallowing but its fine now.he also has twitchy like movements when he finishes eating.is this normal and should i go back to mice?
