I can tell you that the shipment over from South Africa was delayed but it is arriving on Monday. So when you order again from whoever you order from it should be in stock, it was just a hiccup because they never expected it to take off like it did, so stocks ran out. Now though, once the shipment arrives on Monday it will be ongoing with no problems hopefully. The large enhancer is about an inch long round pellet, the small enhancer is roughly half that size, it is exactly the same ingredients, just different sizes. You can see both sizes in the museli, the large enhancer and the small enhancer. My two eat either and love it. You shouldn't have a problem in getting stock now.
