Living World Clay-Cal is a readily available supplement that offers pet birds the benefits of natural geophagy (the consumption of soil or clay). Specifically milled for pet birds, the calcium-rich supplement ensures normal development and can help maintain bones, the nervous system, muscle function, blood clotting and cardiac function. Because seed diets are low in calcium, it is advisable to complement your pet bird's diet with a calcium supplement. Living World Clay-Cal also serves as a digestive aid by helping to neutralize the pH, assisting to bind toxins. Available in a 250 g bag or 500 g container.
