Is it true that cats are in heat in spring and summer only? No, there is no such thing as a generally recognized mating season. Some cats are in heat three, four and sometimes even five times a year, others only two times.
Historical fiction is a literary genre that reconstructs past events in fictional stories. Common characteristics of this writing genre are the inclusion of historical events or historical people, invented scenes and dialogue, as well as authentic and believable details.
Sometimes, historical fiction can be for the most part true, but the names of people and places have been in some way altered. As this is fiction, artistic license is permitted in regard to presentation and subject matter, so long as it does not deviate in significant ways from established history.
