I don't have any experience with ASF's, so I cannot comment on that. However, there are a number of online distributors that will FedEx frozen rats to you, pretty quickly. I purchased from Big Cheese Rodents, and received a well packaged, still frozen, shipment of rats in a matter of a couple of days. I know some people here like to use Rodentpro.com, but I do not have experience with them. Maybe you could hold off on feeding for a couple of days so that you can place and order online, and once they arrive, feed your snake?
