Cats are very dependent on their owners. After their owners leave, the cats appear: they have no energy, lie down obediently, and wait at the door; they go to the rooms and locations where their owners often stay, look for them and call out; they appear first after their owners come home. Behaviors such as running to the door and clinging to the owner are all signs of missing the owner. If the owner is away from home for a long time and cannot take his little cutie with him, it is recommended to place the cat next to a familiar person to reduce the cat’s longing and uneasiness.
