Don't let the little skydiver, cliff hanger up high! LOL jk
I would just keep an eye on his mobility, if he seems to favor 3 limbs over another 1, or doesn't seem to use 1 limb, the typical things you would look for in a cat or dog. Along with, loss of appetite, dark coloration lasting for long periods of time, lethargy.
When these guys take a plunge like that, they tend to flatten out and land on the floor like a pancake with a like sound. :shock:
Anyways doing this spreads the contact surface of their body out and in turn will spread out the shock wave. If they were to land on one leg, just as an example this would keep the impact isolated to one specific area and would be more likely to cause injury.
All in all sounds like it is time for a padded room for the little jumper.
