Cat breeding requires selecting male and female cats of the same breed. When the female cat is in estrus, put the two cats in a room or cage to cultivate their relationship. It takes 1 to 10 minutes for mating. It is best to choose a quiet environment for mating to avoid disturbing the cat. If the male cat is inexperienced, the owner will need to assist him. Depending on the cat's personality, mating will take about 3 days or more. After successful mating, the female cat will scream and scream. Turn around and attack the male cat.
