The snakes are back in Ireland. Folklore tells us that St. Patrick drove all the snakes out of Ireland in his day. Ireland, mainly because of its climate and detachment from the mainland has no native snake species. But that didn't stop people from importing them and keeping them as pets. And as we are seeing happen in Florida so too in Ireland, the fascination with these reptiles fades and people tend to get tired of taking care of them, they grow too large, become too expensive to care for or they escape their cages and these former pets start showing up in the wild and not so wild places. Unicorns make much better pets.
