Feline Spinabifida

Spina bifida is a spinal condition that most often occurs in humans, but is occasionally diagnosed in cats. It occurs in the fetus during embryonic development and is not treatable.

  1. Definition

    • Spina bifida is a congenital defect that results from the inability of the vertebral arch to fuse normally. This occurs during pregnancy, when the fetus is still in the embryonic stage.

    Two Variations

    • When the spinal cord or meninges is protruding (resulting in a sac called a meningocele), the defect is termed spina bifida apida. If there is no protrusion, this is called spina bifida occulta.

    Incidence

    • This condition is rare in felines. However, Manx cats are typically affected supposedly due to their "taillessness".

    Clinical Signs

    • Kittens present with one of a number of symptoms depending on the location of the non-fusion, but usually the defect occurs in the caudal lumbar spine. Signs include motor problems, paralysis, pain, reduced sensation and urinary and/or fecal incontinence.

    Diagnosis

    • Diagnosis is obtained by seeking the help of a veterinarian. An MRI may need to be obtained for a specific diagnosis.

    Treatment

    • There is no treatment for spina bifida. However, if there is an opening in the skin it should be closed to prevent infections or myelomeningitis. Also, if tethering has occurred (wrapping of the spinal cord around the disc), it may be repaired surgically by a veterinary surgeon.
