Animals seem to develop a fear of heights at a very specific developmental stage. Experiments with glass floors over a pit with kittens and babies seem to indicate that you can point to an age when the infant critter will cheerfully crawl/walk over the glass, and a later age when they will refuse to budge. Suggests that the innate fear of falling/heights is wired in and gets turned on at defined point in brain development.

Anyone who has tried to rescue a cat out of/off a tree/roof will know that they really really don't like heights unless they are firmly in control of things. Heavy gloves and a firm grip are prerequisites for completing a rescue unscathed.
