It is much more humane than roaring a cat, exposing it out of the bedroom at night and bringing the unhappy animal and yourself to the stress of the biorhythm mismatch.
It is much more humane not to have a cat at all. I don’t want to follow feeding regimes, win a cat on schedule, look for a place to catch it during trips... And I just don’t catch it. That is all. I don’t bother cats, cats don’t bother me.
