Most animals are just naturally curious. Mine does the same thing when I'm either in the cage or just in the room. And she's been fasting for four months now.
Another example, when I used to hunt crows in a past life; all camo'd up, hiding, using game callers, not an animal in sight. As soon as we would turn on the game caller of say, "fighting crows, or hurt rabbit ", every critter in the woods from within a half mile would show up just out of curiosity,to see what was happening.(Some out of predatation) Birds, squirrels, bobcat, pigs, deer, coons, etc. And crows!
