Cats meow, purr, hiss, and growl to communicate with each other and with humans.
Cats use their body language to communicate their mood, intentions, and feelings.
Cats mark their territory with their scent to let other cats know that this is their space. They do this by rubbing against objects, scratching, and spraying urine.
Purring is a calming and soothing sound that cats make. It is often a sign of contentment or happiness, but it can also be a sign of pain or fear.
Hissing is a warning sign that a cat is feeling threatened or scared. If you see a cat hissing, it is best to back away and give them some space.
Growling is a more aggressive sound that cats make when they are feeling angry or threatened. If you hear a cat growling, it is best to stay away from them.
