I don't know how many of you hate to waste missing link; but I sure do. They sell it in such big bags that if you only have one fur baby, there is so much left over after three months, which is the reccommended time to use a bag. Does anyone know if the missing link goes bad, or loses its strength after that time. I would gladly send someone part of a bag so it doesn't go to waste. I hate to waste the money it costs, but I hate wasting the product more.
