We report unusual foraging events in two of the most invasive terrestrial predators in the world that are well established in the Caribbean islands: the Small Indian Mongoose (Urva auropunctata), locally known as jurón, and the Domestic Cat (Felis catus). The former is well known to be a ground-dwelling species, whereas the latter usually avoids water. We documented tree-climbing in the mongoose and semi-aquatic hunting in a domestic cat. The observations were recorded in southern Dominican Republic, on the island of Hispaniola.
