Cats are nocturnal animals, with excellent vision in darkness or low-light environments, allowing them to move freely in the dark. Although cats feel comfortable in darkness, they also enjoy basking in the sun. Cats like to take naps in warm, sunny spots.

Cats prefer sheltered spaces, often choosing dark or hidden areas to feel safe and protected. These places allow them to better hide and avoid potential threats.

Cats like to hide in boxes, small rooms, or other sheltered spaces, as these areas provide them with a sense of security and comfort.

Through our research, we discovered that in many transparent cat backpacks available on the market, cats tend to feel anxious and uneasy inside the transparent space.

Therefore, when designing our multifunctional rolling cat carrier, we specifically used a brown semi-transparent window. This design provides cats with a sense of security while still allowing owners to observe their cat's condition.
