Re larger walls with dual catflaps, creating a tunnel, this works fine

It also sounds dangerous for the cat, if the flaps jam for some reason

I think it would let you know quickly enough

as for the small closed tunnel, you just leave both flaps open for a few
days (as the bishop said ...) until the cat is used to just going
through unimpeded, then let the flaps down
