Why does a cat arch its back when you touch it?
1. When a stranger pets a cat, the cat may feel nervous, so it arches its back, ready to run away at any time.
2. When a cat arches its back while being petted, it may be a sign that the cat enjoys the touch and is in a happy mood. Arching its back is a way of trying to get its back closer to the owner's hand, so the cat will happily arch its back slightly. Cats are quite adept at expressing their emotions through body language, and arching its back is a response to feeling loved by its owner. Additionally, cats may sniff their owner's face, rub against their body, and purr, all of which express their affection.
