I hate to promote theories that I don't like but here goes. :) It should
be available for comparisons anyway.
Some cats climb trees to eat. That is they take their food into a tree
to eat safely, or to store the food for later. However, I don't think
this is a viable scenario for dromies.
And someone asked about how lions get down from a tree. I saw some footage
on National Geographic (I think) - head first. But the tree didn't have a
vertical trunk either.
