I don't know if Binky was just underweight or if I'm feeding him too much. But, he's turning into a little fatty. I want to get a scale tomorrow to start monitoring his and the rats' weights. He's such a chunk now. I've been following the recommended unlimited pellet/hay diet. But, I'm going to switch him to alfalfa hay too. He might have been underweight. The pet store was only feeding him hay in the morning and some pellets in the morning/evening.
I also bought him a new cage today. I'm not sure when it will get here, but hopefully soon.
He's continuing to be more comfortable around me. He likes to hang out on the bed. And earlier he was following me around my room and sniffing my toes.
