Afternoon session:

He ran pretty well today.  He ran through the first test trial of the sample test-trials, but then he got 5/8 tests of sample-test trials correct.  He got 6/6 in post test trials.  

Yesterday, I fed him 5 pellets, but one pellet was left over in his cage.

I am using an LED taped in place on a cap today.
