Seeking extra attention: The cat may rub against you more frequently, bump you with its head, or try to forcefully intervene in your interactions with another cat.
Aggressive behavior: Cats may exhibit aggression toward another cat or toy, such as slapping, chasing, or snatching toys.
Territorial marking: Cats may mark their territory by using urine or excessive grooming, which may be a warning to newcomers.
Changes in behavior patterns: Cats may become more withdrawn or overly active, or suddenly lose interest in activities they previously enjoyed.
