What happens if you lift a cat by its scruff? - briefly
Lifting a cat by its scruff can cause significant discomfort and distress for the animal. This method of handling is generally not recommended unless absolutely necessary for safety reasons, as it goes against the cat's natural instincts and can lead to fear or aggression.
What happens if you lift a cat by its scruff? - in detail
When a cat is lifted by its scruff, several physiological and behavioral responses occur. The scruff, or nape of the neck, contains sensitive nerve endings that are connected to the cat's autonomic nervous system. This system regulates involuntary body functions such as heart rate, breathing, and digestion.
Upon being lifted by the scruff, a cat may exhibit an immediate change in posture. Its legs will often extend fully, and its tail may stiffen or twitch. This is a reflex action triggered by the stimulation of nerves in the scruff area. The cat's body responds to this perceived threat by preparing for potential fight or flight responses.
Internally, lifting a cat by the scruff can trigger a surge in stress hormones, particularly cortisol and adrenaline. These hormones are part of the "fight or flight" response, designed to help the cat deal with perceived danger. The increased levels of these hormones can lead to an elevated heart rate and blood pressure, preparing the cat for immediate action.
Behaviorally, a cat may become more aggressive or fearful when lifted by its scruff. It might try to claw at the person holding it or attempt to wriggle free. This behavior is a natural response to feeling restrained and threatened. In some cases, cats may also vocalize loudly as a sign of distress.
Prolonged lifting by the scruff can lead to physical discomfort or even injury for the cat. The scruff area is sensitive and can be easily damaged if too much force is applied. Additionally, the cat's body weight being supported solely by the scruff can cause strain on the neck muscles and potentially lead to muscle fatigue or injury over time.
It is important to note that while kittens are often carried by their mothers using the scruff, this action is different from a human lifting an adult cat by its scruff. Kittens have a higher tolerance for being lifted in this manner due to their smaller size and the protective instincts of their mother. Adult cats do not have the same level of tolerance or protection and may react more negatively to being lifted by the scruff.
In summary, lifting a cat by its scruff triggers a cascade of physiological and behavioral responses designed to help the cat deal with perceived danger. While it is a natural reflex action for kittens carried by their mothers, it can cause stress, discomfort, and potential injury in adult cats when performed by humans.
