While it might not be laughter or a smile in the way humans understand, they display happiness and contentment through purring, relaxed eyes, and an upright tail.
Purring is a common sign of a content cat, and it's often accompanied by kneading, which is a sign of pure joy.
Cats also don't smile in the human sense. However, when they're comfortable and relaxed, their facial muscles may appear to form a slight "smile."
An arched back and puffed-up tail can indicate fear or aggression, while a relaxed posture and a slow blink are signs of a happy and content cat.
Chasing toys, pouncing, and engaging in interactive play with their owners are all signs of a delighted and entertained feline.
While cats may not laugh and smile like humans, they have their unique ways of expressing emotions.
Cats have their language of expressions that may not mimic human laughter or smiling, but they can show happiness, contentment, and trust in their own distinct ways.
