There were various persons, including the son of my neighbor, that saw a black panther with a kitten near the house. That is approx 200 - 300 meters down the property in a forest near lake Arenal. A while ago there were also sightings of a puma and most probably a bobcat (according the description of the persons that saw them) Unfortunately, it did cost the life of a few chickens, a dog and a calf. So people has scared them away, killing is forbidden in Costa Rica. (fortunately)
Costa Rica, pura vida
