Whether a cat remembers his owner after one month away depends on the cat's age and individual memory differences. Under normal circumstances, kittens may forget their owners. If the cat is an adult or has a good memory, it will still be able to recognize the owner when it sees him again even if it is separated for several months.

Scientific research shows that cats’ IQ is equivalent to that of a 2-3-year-old human, and they have long-term memory. Historically, cats were hunters before they were domesticated and needed to rely on learning and memorizing hunting methods and strategies to survive in the wild. In addition, in order to ensure that cats can return safely after hunting, cats need to remember their own movement routes, smells, sounds, and dangerous areas. Therefore, cats have a strong ability to identify and recognize home. Cats that are free range or often play outside can usually find their way home. Naturally, the owner's scent can also form a deeper memory for the cat.

If a cat leaves its owner and goes to a completely unfamiliar place, because there is no image or smell related to the owner in the environment, the cat's memory of the original owner may begin to fade in order to better adapt to the new environment. Once the time is too long, it may cause forgetfulness.
