@tsarstepan,
Mr. tsar, Do not cast an aspersion on a gibbon. It was hard enough accepting their downgrade to lesser apes. Naturalists. Biologists. Scientists. What do they know?
There is (or was) a gibbon island in the Bronx Zoo. These animals are smart, agile, and athletic. They fly through the air from branch to branch. Amazing creatures--and from this planet. Just read that they can cover 9 meters in a single leap (however long that is).
Not commenting on your jaguar cub suspicions.
