Yeah well, worth attempting the first time in your run, then maybe use the corner backup afterwards if it fails. It works on 60fps and uncapped as far as I'm aware. You can also try it multiple times, starting from the stairs in front of the door, you'll acquire enough speed.

It's important to go either to the right or the left of the door, because the "scratch" action will move the cat towards the middle of it, which will then allow you to clip through. If you go straight for the middle, it won't work.
