Oh, totally! My Shikoku does that all the time. It's like they're little statues when they spot something intriguing.

My Shikoku can get really focused on small movements too. It's like they go into hunting mode. I once watched mine track a squirrel for over ten minutes without budging. They have this intense gaze, which is super cute but also a little concerning when you realize how much they want to chase it!
