Cats walking upright are harmful to bone health. Since cats' body structure and behavior are not designed to walk upright, long-term doing so will put extra pressure on their spines, which may cause various skeletal problems. Cats will occasionally choose to walk upright to raise their field of view and amuse their owners. They will also adopt this posture when they are frightened or want to show off their powerful body to drive away enemies.

In addition, when playing, they may also choose to walk upright, but these behaviors are not normal. If the cat owner finds that the cat frequently walks upright, it is recommended to take it to the hospital for examination in time.
