Animals can show curiosity by approaching the object of their curiosity cautiously, sniffing at it, pawing at it, and/or lightly scratching, biting, or pushing it. Usually, a curious animal starts out with a lot of caution when approaching an object, but once they determine it is not a threat, they will try to figure out its function. They will see how it tastes to determine if it's food. They will move it around to see it from different angles and determine if it's a toy. If it isn't food, isn't alive, and won't make a good toy, most animals lose interest quickly.
