You know what I just thought about. Having a mess on the floor with lots of items strewn all over the place isn't a big deal with a parrot. With my parrot it is really important not to leave anything out on counters/tables but having things all over the floor hardly matters. Furthermore, unlike a terrestrial pet, my parrot can fly over everything without stepping in it. Meanwhile a floor based mess might inhibit or get spread by a cat/dog. Just an observation I wanted to share.
I don't like clutter and tend to avoid it. I just finished polishing up the apartment after the move and it makes me terribly happy.
Parrots also generate "mess". Fortunately, mine are pretty good about keeping it within boundaries (not strewn all over the place). And having the cages in a separate room helps keep the living room cleaner
