Obviously, nipping and biting behaviour from your pet is less than ideal, and for a number of reasons it’s important to limit it. Realistically, they’re natural behaviours for dogs and cats. In fact, they’re natural behaviours for kids too! What's the first thing an infant does when it grasps something new? Chances are, it goes in the mouth, and if it's fun or feels good it happens again! It’s exactly the same for cats and dogs. That said, when it comes to your cats and dogs, you need to draw a line to make sure you have a happy, well-socialised pet who doesn’t terrorise the family or the neighbourhood.
