What should I do if a female cat attacks a person for protecting her cubs?

If it is the kind of stray cat you can first slowly cultivate the relationship, give food and canned food every day, in time it will become familiar with the person who feeds it, so that it can slowly get in touch with the mother cat and the cubs. A mother cat is protective of her cubs during the nursing period and may be aggressive, but this is usually the case with unfamiliar people. If she is still nursing at this time, she will not only guard against it, but may also take the initiative to expel anything she considers threatening from her territory. Therefore, during pregnancy and lactation, it is best for the mother cat to be in the environment she is most familiar with. If the mother cat is very familiar with the environment and the caregivers, she will rarely act aggressively. Some cats will even feel comfortable leaving their young in the hands of a familiar owner.
