Vitakraft Bursts are small, pillow-shaped nibble treats built with a crunchy outer shell and a soft, fruit-flavored center. The shell is formed primarily from oat flour, wheat flour, and ground timothy grass hay, giving it a crisp texture meant to encourage natural chewing. The center is made with a blend of blackberry, blueberry, and raspberry powders, contributing natural vitamin C that is useful for guinea pigs. Each pouch is ready to serve directly with no assembly or preparation needed. The treats are intended as a supplemental snack alongside a pet's regular hay and pellet diet rather than a primary food source. Fresh, clean water should remain available whenever treats are offered.
