Why do cats like cardboard boxes?
Many cats love cardboard boxes because they are a safe and fun place for them, providing a secluded space as well as a hiding place, resting spot, and play area. Furthermore, cats often use cardboard boxes as observation points, peering into their surroundings to satisfy their curiosity. 
From a cat's nature, they are born explorers and hunters. Cardboard boxes provide a place similar to a cave or tree hollow, making cats feel comfortable and safe, which is why cats love cardboard boxes.
To better meet your cat's needs, you can continuously provide new cardboard boxes and place them in appropriate locations to help relieve stress and enhance their sense of trust and exploration. In addition, you can stimulate your cat's interest by putting small balls, toys, etc., in the boxes, making their playtime more enjoyable and relaxing.
