I have noticed my sully often does this, she comes to her food, then for no reason, she HAVE to go back and make a quick U-turn for no reason and comeback to the dish, she can do that many times before finishing instead of just standing there and eat, then Iv’e noticed others older sully do the same! So what is the reason for that behavior, testing to see if something try to chase them? Can’t eat too long at the same place because they are programmed to eat while always moving??
