The crab walk is a feline behavior that may be exhibited when a cat feels anxious or threatened. When performing the crab walk, a cat will lower its body close to the ground and move sideways. This position allows the cat to appear larger and more intimidating, which may deter potential threats. Additionally, the crab walk gives cats a better view of their surroundings and helps them to identify escape routes.
While the crab walk may be used as a defensive tactic, it can also be seen as part of play behavior or during periods of excitement. For example, kittens often engage in mock fighting using the crab walk stance. So, if you see your cat performing the crab walk, it could simply mean that they're feeling playful or happy.
