Rectricectomy With Pygostylectomy for Resolution of Feather Trauma in an Umbrella Cockatoo ().

Feather trauma is a common problem among pet birds, especially those with trimmed wing feathers, and often affects remiges and rectrices. Damage can become chronic if new feathers remain unprotected by fully formed adjacent feathers. The follicles can become damaged and poorly functional over time.

Establishing Stress Behaviors in Response to Manual Restraint in Cockatiels ().

Avian patients are presented commonly to veterinarians for preventive and disease-induced care. Physical examinations commonly are used to assess the overall patient, but this requires manual restraint, which often leads to increased stress and subsequent deleterious effects. To develop a noninvasive evaluation of the stress response in cockatiels (), we evaluated the behavior of 26 juvenile cockatiels during their normal daily routine and after an acute stressful event (manual restraint and physical examination).

Antemortem diagnosis and successful management of noncompressive segmental myelopathy in a Siberian-Bengal mixed breed tiger.

A 10-yr-old female spayed mixed breed tiger presented for a 9-day history of acute and nonprogressive paralysis of the pelvic limbs. Magnetic resonance imaging revealed a lesion suggestive of fibrocartilaginous embolic myelopathy with regional spinal cord edema, decreased disk signal intensity at L2-L3, and mild intervertebral disk protrusion at L1-L2 and L2-L3. Cerebral spinal fluid analysis showed no overt evidence of infection or neoplasia.
