Normal?

I thought it would be a good idea to read some child-development books so I can better understand my child.  Here's what I learned:

Cats are supreme tree-climbing hunters, with strongly muscled backs and hindquarters that give them tremendous power to jump - either horizontally or vertically.  It's normal for cats to jump and climb to high places as they explore their environment.

There's nothing to be concerned about; Kitty is perfectly normal.
