Thorns are present in native blackberry plants and the thorns prevent grazing wildlife, animals and birds from eating the vines before the berry bushes flower and later when blackberries are produced. When the blackberries grow and ripen, they are not only consumed by wildlife animals and birds, but they have been enjoyed by humans for centuries. Luther Burbank wrote in his book, Fruit Improvement, in 1921 that many hybrids had been developed by his efforts and others to grow thornless blackberry bushes and vines. These thornless creations were at first inferior in taste and quality to the thorny species; however, modern hybridizers of thornless blackberry plants have created the cultivars:
Cats Claw (una de gato); Cat's Claw is a tropical vine that grows in rainforest. This vine gets its name from the small thorns at the base of the leaves, which looks like a cat's claw.

The inner bark of this vine has been used for generations to treat inflammations, colds, viral infections, arthritis, and tumors.
