The clingy behaviors of cats include rubbing against people, sleeping with people, purring, showing their belly, sneak attacks, making trouble, etc. These are all signs that cats like to be clingy. If you want your cat to become clingy, you can feed it more of its favorite snacks, such as canned cats, freeze-dried cats, cat strips, etc. You can also sprinkle some catnip on the ground, which will make the cat feel better and make it easier to get close to him. .
