All children need to learn animals bite. This is especially true of wild animals, but it is also true of pets. The bigger you are to them, and the louder, the more you scare them. If you grab them suddenly, or make them feel trapped and unable to get away from you, they get terrified. They are scared and terrified because they think you are a predator going to hurt or kill them. They don't have voices to tell you this, so they use teeth. So it's your job to speak softly, remember how big you look to them, and make sure you handle them in a way they can feel they can get away if they want to.
