I saw that show. Besides the obvious with the snakes; the pigs are some type of warthog, and the rats are freakin' the size of cats (10 lbs!)...come to think of it having burms around wouldn't be such a bad idea then...ANYWAYS, back to the topic. We have some feral warthogs here in Charleston, SC. They mainly live on the islands along the coast. As for the rats, they had another show on Animal Planet about how these particular rats are trained to sniff out Tuberculosis and Land Mines. There's good and bad in everything I suppose, it's all in how it's put into context.
Oh, we also have armadillos running around in SC too... redneck road lobster
