To follow up,

My guy was active today around 3:30pm which was a clear indication he was hungry again and I knew he gave up the previous night by 10pm.

We fed him at 9pm. He actually tried to strike the small rat though the mesh when it was under the light. At that point I offered it to him and he took it right away. Gave the rail a few 5-10 sec tugs and he was off the the races.

He started this one on his rock and then moved in to hot side hide to finishing swallowing it.

10 days again, this feed should officially put us past 600 grams.
