The well-fed house cat is an unmotivated and clumsy hunter. However, your cat still has the skills and instincts of a born predator. This shows up as play – stalking, pouncing, chasing anything that moves, and ambushing you or other companion animals are all feline ways of having a good time.
Overstimulation is the swatting or biting behavior that cats exhibit in response to too much petting. Oftentimes, cats who are easily overstimulated are friendly cats who will seek attention from people, but then strike out after a short period of petting. The cause of overstimulation is not known, but there are ways to reduce the incidences of biting and swatting.
Many people believe that cats are too independent or apathetic to respond to people's attempts to modify their behavior. But the failures people have experienced when attempting to alter their cat's behavior are not the fault of the cat. Rather, they are misunderstandings between humans and felines.
