The locking mechanism does not lock only opening the door inward, but outward. This makes it possible for foreign cats, / with their claws to pull the door with his paw to the outside and so to come through the door.
For me a clear bad investment!
To block out the foreign cat I close the lid GNTB. When I get home I do not completely and thus my cat or. That's then but not the purpose of a cat flap!
