There is a way you can ID the Cuban frog. I have a "butterfly" net from the dollar store in which I catch them. Hold them in the net, away from you because they do pee ! Try to rub the skin on the forehead; if it's fused, it's a Cuban frog. Then you can put some teeth soothing gel (like Ambisol) on it's head and back (stuff used for toothache); put in plastic bag and into your freezer. Remove 3-4 days later and toss with garbage. You can google this with the University of Florida; It's the most humane way.
