The required facial muscles and vocal cords to produce laughing sounds are absent in cats, physically limiting vocal laughter.
Anatomy
Happy cats express joy and affection by purring and kneading when content, not through laughter vocalizations.
Purring
Relaxed ears, affectionate bunting, upright tail, and kneading paws display a cat’s lighthearted happiness without laughing.
Body Language
Some cats seem to smile or vocalize chirpy notes reflecting inner amusement befitting their character.
Individuality
Playful interactions with catnip toys, tasty treats, or gentle petting can elicit happy kitty delight too.
Stimulation
Shared laughter fortifies human-feline bonds so interpret your cat's quirky chirps during playtime as their laughter.
Bonding
While cats can't laugh like humans, attentive owners can learn to interpret their cat's unique expressions of joy and silly contentment.
