We aren't supposed to have wolves here either, but they are around. What happens is someone raises them as pets and they get away or are dumped. They find their way back to a human population since they think of people as a food source, then they are spotted and eventually trapped by Wildlife and Fisheries. I'm sure some of them survive for a while and are shot by hunters thinking they are coyotes. I shot 2 coyotes last year and didn't even walk over to check them out. They could have been wolves and I would never know.
We have plenty of cougars even though they tell us the population is small. We weren't supposed to have black bears this far north either, but two years ago one wound up in a residential subdivision in Bossier City. Oops. Pet dumping has put lots of weird things out there. We have tilapia and pirana in some of our lakes and rivers, and plenty of pythons and other exotic snakes in our swamps. This year Dallas police found a dead tiger in the city limits; good thing they shot it instead of dumping it in the woods. There's a bunch of African feral cats out there, too. In New Orleans, we have a large population of wild parrots, cockatoos, cockateils, and budgies. One year we had two red Macaws nest in a tree behind our courtyard. That was pretty cool.
There's too much running loose out there for me to say from here that someone hasn't seen something where it shouldn't exist.
Except Bigfoot.
