For the period of this time, stay your female cat away from any doors, or unmoved male cats. Even the most docile cat will try to get away and find a male to breed with. To avoid the risk of losing your cat, having her injured by a hostile male, receiving a disease, or having a not needed litter of kittens spay your female cat. There are other ways to keep it calm like artificial insertion in its vigina but I do not suggest it. Bring it a male partner is a better option.
