Cats typically exhibit estrus symptoms between March and April or November and December, primarily during seasonal transitions. This estrus cycle is influenced by hormonal fluctuations and occurs periodically. When in heat, cats often become more affectionate and vocalize to attract the attention of other cats of the opposite sex and their owners.

During a cat's heat cycle, it is essential to keep doors and windows closed, or even completely sealed off. This is because cats experience a surge in hormones during this time, which can make them more irritable. Even if screens are closed, they may still open or break them.
