Down in the bayou country they have those giant aquatic rodents, nutria I think they are called. The swamp people eat them and why not? I think the big snakes need really warm temps year round. We have walking catfish in Florida. This used to be a nice place to live when I was a kid. We have coyotes in the county here in central Florida. I know that is no big deal in Texas but it is a big deal in Florida. The natural predators have been wiped out (bobcats and panthers). The alligator is the main predator and there are about 1,000,000 of them in Fla.
