FYI - He happily NAILED his mouse tonight and got it right down! Hungry boy. He wasn't interested in the rat either because it was foreign to him and/or he was in blue. I'll try again soon.
In the meantime, happy he's back to nailing mice! He was on a two-week feeding schedule, but since he ate almost 3 weeks ago, I fed him tonight and will feed again in about 8 days.
