The pelvis is composed of 4 bones (ilium, ischium, pubis, and sacrum) that form a box to connect the spine to both of the hind limbs at the hip joints. The pelvic box surrounds and protects portions of the intestinal, urinary, and reproductive tracts. Common problems with the pelvis include fractures from trauma and arthritis. Due to the box-like nature of the pelvis, fractures tend to be multiple and concomitant injury to the internal organs may occur. Cats with hip pain may rise more slowly or limp; many cats will appear lazy, preferring to sleep. A healthy body weight is the best insurance to minimize joint inflammation in your cat’s later years. Anti-inflammatory medications, nutritional supplements, physical therapy, and/or surgery may be recommended by your veterinarian to keep the hip joints strong and mobile.
