Sitting in dangerous places!

Hi guys,
So tiny monster has decided that he is now going to perch on top of one of the doors in our house. Its a good 7ft and about an inch thick. He's done it once and been rescued, he looked pretty scared but I'm terrified he is going to do it again. I don't feel its safe for him and the jump down is on to a hard floor so i dont know how his dabs would have taken it.
Am i overreacting? I feel like i might be overreacting.
He has lots of places to climb normally but this is a new door to him.
If this is an issue how can i make sure he doesn't do it? It's impossible to put a safe path down in.

Here is his beautiful baby face (which makes him look small but I assure you he is probably half panther by the size of him)

Sorry, makes me laugh!  They are so good at climbing up but not so much on the going down.  My precious decreased cat would jump from the second floor to the couch below.  Usually only to show off for company.  At least he was an adult.  Really don't know how to solve this except to find a way to remove access.  Shut doors with ever you can & maybe he will forget & look elsewhere for fun!  Good luck!
