The female cat is very resistant to male cats, which may be caused by the female cat’s unfamiliarity with the male cat, the male cat does not conform to the cat’s aesthetics, and the female cat is not in estrus. If the female cat has reached the age of maturity but has not been in estrus, it may be caused by the female cat's late maturity or malnutrition.
Therefore, pet owners can find a cat that suits the aesthetics and let them spend time together. Then they may fall in love over time, and the female cat will not reject the male cat.
Be careful to check the cat's body before it is closed and avoid infection with certain infectious diseases.
