Unfortunately, you need longer than that to get CITIES paperwork. If you wanted to come down for animals, i would have started that process already and starting it now is REALLY pushing it. There is also a fee for CITIES and its not very cheap if i recall.
Also, even when doing things to prepare for a show, to ask for something as complicated as CITIES a -week- before a show that big is pretty unreasonable. We can't get the paperwork done as fast here as canada it seems. Breeders, especially large ones spend WEEKS preparing for a show.
