Keep your door open by having a drink

This is a really simple Lifehack. A few weeks ago we got a little pirate on loan. His name is Joey. We're used to keeping all doors closed, and now we have to give the little cat a route to his private toilet. We were afraid we would inadvertently close the door on the cat when nature calls. However, we don't have one of those gadgets for keeping the door open.

After a minute I came up with an idea: let's put a cork in the doorframe. It's invisible, always there and free. And we already have a few in the house. If you want to customize the open 'angle' of your door, you can cut the cork. If you're not satisfied with the result, have another bottle of wine...

Have you got any tricks with wine bottles or corks? Tell me in the comments!
