Cats cry or meow at night for several common reasons: they are naturally more active at dawn and dusk, which can make them vocal at night due to their crepuscular nature. They may be bored, seeking attention, or hungry. Medical issues such as hyperthyroidism, pain, or cognitive decline in older cats can also cause nighttime vocalization. Outdoor cats might feel confined indoors, leading to crying. Additionally, cats in heat or mating phase yowl at night. Changes in the environment or anxiety can also be triggers. To address this, it’s important to check for health issues with a vet, ensure the cat has enough play and mental stimulation during the day, provide late-night feeding, and create a comforting environment at night.
