Adult Animals: All animals over four months must have food taken away the night before surgery at 10:00 pm. This will ensure that the animals's stomach has emptied by the time he's put under general anesthesia. This lessens the chances that your pet will vomit and aspirate the vomit into his lungs. Do not withhold water prior to surgery.
Pediatric Animals: Animals four months or younger should have food available until 6:00AM on the morning of surgery to avoid decreased blood sugar level. Do not withhold water prior to surgery.
