Lol nope, he just goes about what he's doing like you weren't there unless you wiggle a finger next to him. Then he slowly creeps up closer and closer to the finger with tongue flicking. He did that to my hand a few days ago when i was changing his paper towels on the floor. I thought i was going to get tagged but after some intensive tongue flicking, he back tracked and recurled on his perch and went back to bed. Guess my hand didnt smell like a nice juicy fuzzy mouse lol. That pic of him above is him noticing my finger wiggling at him and him creeping closer.
