Is your American Bobtail having trouble moving around? If so, you may want to call your vet and schedule a checkup. Your bobtail’s lack of mobility could be from a number of things including arthritis, Degenerative Joint Disease (DJD), or Schiff-Sherrington phenomenon. Schiff-Sherrington phenomenon occurs when the cat’s spinal cord is severed or cut across by a small yet severe lesion on the cat’s lower back (usually the second lumbar vertebrae). This causes an extreme posturing of the upper limbs. The hind limbs may also suffer from paralysis or loss of strength and muscle. This occurs due to the damage to the border cells and interneurons that are located in the second lumbar vertebrae. The overall result is pain and the inability for the cat to move as she did once before. Your vet services Richardson, TX will need to examine your cat to determine if this is the problem. Not all cats with mobility issues have Schiff-Sherrington phenomenon.
