Indoor cats are domesticated felines that live primarily inside homes rather than outdoors. They are often kept as pets for companionship and can provide emotional support to their owners. Indoor cats typically have a longer lifespan than outdoor cats due to reduced risks from predators, diseases, and accidents. To keep indoor cats happy and healthy, owners should provide stimulating environments with toys, scratching posts, and climbing structures. Regular playtime and interaction are essential for their mental and physical well-being. Additionally, indoor cats require a balanced diet and regular veterinary check-ups to maintain their health.
