Alternatives to traditional catnip include offering cats interactive play sessions, which help keep them mentally stimulated and physically fit. Creating cozy hidey-holes like kitty condos or using boxes can provide comfort and security. Window views allow cats to observe outdoor activities, such as watching birds or squirrels, offering entertainment and relaxation. A good scratching post helps cats maintain healthy claws while preventing furniture damage. These simple but engaging options offer cats a variety of enjoyable activities without relying solely on catnip for stimulation.
