The soaring demand for protein poses a real challenge, because current available supplies just can't keep up. This gap between protein supply and demand is expected to continue to expand as the world population and global pet ownership increases. From alligator, kangaroo, buffalo and brushtail possum in dog and cat treats petfood companies have are cleverly catering to growing consumer demand for ever more exotic and novel sources of protein. Just as people are seeking to try new types, and increase the levels, of protein in the foods they eat, they are doing the same for their pets' foods, thanks to ongoing humanisation. Many plant-based proteins have been widely used in human and animal nutrition for years such as soybeans, peas, lupin beans, potatoes, wheat and corn. Other meat analogues and the development of e.g. vegan canine biscuits, are just now starting to become popular and widely available.
