On Wednesday, October 24th Coconut, the snow leopard cub born at the Sacramento Zoo earlier this year, will be the recipient of a rare eyelid surgery performed by Sacramento Zoo veterinarians as well as veterinary specialists from UC Davis.
Shortly after his birth, it was discovered that Coconut had visible birth defects. This eyelid surgery has been a possibility since UC Davis and Sacramento Zoo veterinarians first examined the young cub. In addition to his mobility issues, Coconut was also born with eyelid defects, known as colombas. This ocular deformity is sometimes documented in snow leopards under human care.
After months of regular monitoring by Sacramento Zoo care staff, as well as daily eye drops and periodic examinations by UC Davis specialists, the decision to proceed with the eyelid surgery was made late September.
Since his birth, the zoo’s animal care team has been working tirelessly with Coconut to help treat his physical deformities. Their consistent care, therapy, training and socialization have all prepared Coconut for this or any other potential surgery, and for a successful recovery in the future. Most recently, Coconut’s keeper staff has been working with him to take voluntary injections through the use of operant conditioning training. This keeper/animal relationship building and established trust will be helpful for Coconut’s upcoming surgery and will aid in routine care, husbandry, veterinary care and potential transportation in the future.
On Wednesday, animal care staff will anesthetize Coconut at the Sacramento Zoo for an ophthalmic evaluation and surgery to address his congenital eyelid deformity. An orthopedic specialist from UC Davis will also perform an evaluation to assess the cub’s muscles and bones related to a developmental abnormality commonly referred to as “swimmer’s syndrome”. The surgery will be performed on zoo grounds at the Dr. Murray E. Fowler Veterinary Hospital. The surgery, which will begin at approximately 9:30 a.m., will be open to the public via our viewing window at the hospital.
Specific treatment will be determined by specialists while the cub is under anesthesia. Options vary from eyelid hair follicle freezing (cryotherapy) to partial eyelid removal (bilateral simple wedge resection). Coconut’s recovery time post-surgery will depend on the specific treatment, but the young cat will be off exhibit for at least two weeks to allow him proper time to recover and heal.
