In the early 1970s, Dr. Shirley McGreal, OBE, and her husband John were living in Thailand, where she became aware of the mistreatment of animals in the exotic pet trade. Determined to make a difference, she founded the International Primate Protection League (IPPL) and later established a sanctuary in Summerville, South Carolina. There, gibbons—and a few otters—are given safe, lifelong homes, far from roadside zoos, medical experiments, and other harmful fates.
Located less than seven miles from the Katie’s Krops flagship garden, the sanctuary is home to 23 gibbons, most of whom are frugivores who thrive on a wide variety of fruits and vegetables. Their favorites include root vegetables, squashes, peppers, eggplants, pea pods, tomatoes, berries, apples, cucumbers, nuts, and kiwi—just to name a few from the more than 50 foods they enjoy. But not everything is a hit: kohlrabi, artichokes, and rainbow Swiss chard are on their “no, thank you” list.
As David Kibbel, volunteer coordinator and animal keeper, explains, “Feeding the gibbons is like feeding 23 furry, lovable, and opinionated kids, each with their own tastes and preferences.” Beyond preferences, though, the staff also has to carefully consider dietary and medical needs, such as managing lower-sugar diets for those with diabetes.


Katie’s Krops began supporting IPPL in 2020. To help offset the cost of feeding the gibbons two meals a day, IPPL created a vegetable garden using seeds and plants provided by Katie’s Krops, along with the help of volunteers. Occasionally, the sanctuary also receives produce harvested from our flagship garden. This year, we are helping expand their growing capacity by adding a new 42-by-36-foot garden bed and donating Soil³ compost—the same product we use in our own gardens. These efforts have already resulted in harvests of eggplant, sweet potatoes, cherry tomatoes, and okra during the hot South Carolina summer. The homegrown produce, especially the okra, has been a big hit with the gibbons, who seem to prefer it over store-bought.
Katie’s Krops is proud to support the humanitarian and animal welfare work of IPPL, and we encourage others to do the same.
