My cat scratches my door! Help me ZzZzZ

I have a 10 year old kitty that i love dearly. Ive had her since she was a kitten. My issue here is closed doors. The only door i close is the bedroom door at night when i am sleeping. I dont know if its territorial, or a control thing, but if she sees a closed door, it needs to be open. So she scratches the bottom of the door which is tearing it up, (not declawed, and no i wont declaw her), and is the most annoying thing ever. This had gone on before but she quit doing it, but has started again. :(

I've never really tried anything to get her to stop, other than ignoring her which just makes her scratch more. (Going to try double sided tape tonight). Anyone else have this problem (or other cat problems... feel free to share), and have found a fix?

I also feel...this being OT, that i need to add keeping the door is not an option and neither is declawing her. But i think thats obvious. 

Spray it with water when it scratches the door.Co0kieMonsterxX

Diamond coat the door.thriteenthmonke

Put one of those cat scratching mat thingies on the door and she won't mess up the door and you probably won't hear it.

Or like put a doggy ddoor there.
