There is a room in my house where I do my carpentry work. That room is full of dust and wood debris and I don't want my cat to go in there because I don't want it to come out dusty and I am afraid it could get hurt on the sharp objects in there. So I keep the door shut.
The problem is that my cat would oftenly sit in front of that door and start meowing for hours and will only stop if I let it in. It does that no matter if I am in the room or not. How can I make it forget about wanting to go in that room?
