If your cat likes to open doors and run away, I have a solution for you, here's a simple, printed-in-place door handle lock. Very little material consumption, after printing all you need is to give a "gentle" slap on the hinge and wiggle to release the movement.
Use strong adhesive tape to attach and that's it.
