Okay... and for my third hello post... Hi-Chew is pretty aggressive, like definitely the alpha rat here. He always seems to be winning their playfights and if we give Tapioca a treat he'll steal it away. I generally feed Hi-Chew first to distract him and then give Tapioca something. Otherwise I'm sure Hi-Chew would take it all! He's gonna get fat at this rate. We've only had them a week and a half and it even looks like Hi-Chew is bigger than Tapioca. We'll see how it pans out when they're full grown, I guess.
