Saving the life of a collapsed horse, fixing a dog’s broken leg and giving mouth-to-beak resuscitation to an endangered Hawaiian coot is pretty much a normal day for Kauai veterinarian Scott Sims. Unless he has to operate on a goat’s hernia, which he takes in stride as well.

The 59-year-old Sims runs the most unique animal-care practice in Hawaii. In addition to treating animals of every size and temperament, he makes house calls to other islands — in a plane he built himself. And barefoot, too.

If all that sounds too crazy to be true — and Sims would agree that it’s pretty crazy — see for yourself when Nat Geo Wild premieres "Aloha Vet" at 3 p.m. Saturday, with an encore at 6 p.m.

The series follows Sims through eight episodes shot last fall.

Sims, who moved from Northern Cali­for­nia to Hawaii about 14 years ago, runs his veterinary practice out of his home in Kilauea. He works 12 to 14 hours almost every day.

"I see a tremendous variety of animals," Sims said. "I’m not your average dog and cat vet. I’m foolish enough to take on just about any case."
