How to stop a fearful cat from biting
Act calmly.
Do not respond wildly to a cat that is biting you out of fear. If you act out in shock and pain it is likely that the cat's fear will increase and its biting will increase in response.

Options are:
(A). First try to remain calm throughout the interaction. In no time the cat will be deterred and will stop using you..
(B). The cat will more likely become scared and aggressive if you react methodically and calmly. The cat can interpret your reaction as fear and it will be more likely to mimic this behaviour..
(C). Instead, take a deep breath and move forward calmly with a plan to get the cat to let go. It can be hard to not respond strongly to a cat bite that you don't see coming..
(D). Instead, make a calm exit away from the cat. If you do not react calmly to a cat that is biting you, it will spend less time and energy engaging with you..
(C).
