Cats who can’t hide their desire to shovel their feces show up by biting their owners vigorously. When a cat bites you deliberately and painfully, it means that the cat hates you. It’s not that they don’t control the strength well. But do it intentionally.
If your cat shows a fierce look towards you, If the cat often vents its anger on you, always looks fierce at you, bares its teeth, and keeps breathing, it means that the cat hates you very much, or even hates you very much. It cannot hide its desire to kill you.
