How to Tell If Your Cat's Rear Quarters Are Healthy
Cats showing any of the signs above should be taken to their veterinary clinic without delay to ensure proper examination, diagnosis, and treatment.
Spinal Column
The spinal column runs the entire length of the body, from where it joins the head to the middle of the tail. Also called the spinal canal, it consists of the backbone (vertebral column), which encloses the spinal cord. This spinal cord is the "message center" of the body and operates through nerve endings to control the functions of all parts of the body. Nerve endings also convey sensations of feeling, such as heat, cold, and pain. The spinal cord is one of the most important organs of the body.
The spinal column in a healthy cat is extremely flexible, which allows for the agility for which cats are famous. A falling cat can right itself by twisting its spine to be able to land upright on its feet. The spine of a cat in a relaxed four-legs stance will be fairly straight and parallel to the ground, sloping down slightly from the front shoulders and again toward the base of the tail.
