What is what does it mean when a cat arches their back?

A cat arching its back can mean a few different things, and it's important to consider the context to understand the cat's intent. Here's a breakdown:

• Stretching: A cat will often arch its back as part of a stretch after waking up or after a period of inactivity. This is usually accompanied by extending its front legs forward and may involve a slight tail twitch. This is a normal and healthy behavior.
• Feeling Threatened or Defensive (Halloween Cat Pose): This is perhaps the most recognizable arched-back posture. When a cat feels threatened, scared, or aggressive, it will try to make itself look bigger and more intimidating. This involves arching the back, puffing up the fur (especially along the back and tail), turning sideways to the perceived threat, hissing, and sometimes spitting.

• Greeting or Seeking Attention: Sometimes, a cat will arch its back while rubbing against your legs or objects. This is often accompanied by purring and meowing, and indicates that the cat is seeking attention, affection, or is simply greeting you. The cat is essentially offering its back for you to scratch.

• Pain or Discomfort: In some cases, a cat arching its back can indicate pain or discomfort, especially if it's a hunched posture and accompanied by other signs like reluctance to move, changes in appetite, or vocalization. This is more likely if the posture is unusual for the cat, and is sustained for an extended period.
