Cats meow at night primarily because of their natural activity patterns, needs, and possible health or emotional issues. Cats are crepuscular animals, most active at dawn and dusk, so they often have more energy and vocalize during the quiet nighttime hours. Common reasons for nighttime meowing include seeking attention or companionship because they feel lonely or bored, hunger if meals are spaced too far apart, medical conditions such as hyperthyroidism or kidney issues causing discomfort or increased appetite, and age-related cognitive decline or anxiety. Outdoor cats confined indoors at night or changes in environment can also cause vocalizations. Older cats may meow more due to physical discomfort or confusion. Addressing these causes with daytime play, scheduled feeding, veterinary checks, and providing enrichment can often reduce nighttime meowing.
