You know, my birds did far mor damage clipped than flighted. When clipped they spent far more time wandering around on the floor to get where the wanted to go and climbing on things like my bookshelves. They have been flighted far longer than they were ever clipped and yet the loss of electrical equipment, books, Tupperware, clothing, mostly occurred when they were young and clipped, not older and flighted. Either they have become less destructive or there's a difference between flighted and not flighted!
As for having other pets in the house, I'd rather have a fully flighted parrot who can get away from a preditor than a clipped parrot who cannot. I lived harmoniously with cats and parrots for many years and never once had a problem. The parrots actually tormented the cats and I was more worried about the cats' safety than the parrots' safety. We now have indoor mini chickens and one of our hens has a huge vendetta against our Galahs to the point that she will chase them down any chance she gets and she means business. I've never been more happy that my birds are fully flighted and can out maneuver her because they need every advantage they can get when it comes down to the Queen Bee Miss Tildie!
. Of course the dumb thing is that they could inflict an enormous amount of damage on this tiny chicken if they wanted to but they are completely terrified of her and just stay out of her way and everyone is happy.
Finally, the study done in the UK on lost birds showed that more birds that got out were clipped than fully flighted and this was most likely due to the fact that people who clip their birds have a false sense of security that their birds can't or won't fly away where those of us who have fully flighted birds tend to more careful (although not always as I am a member of the "Outdoor Flight" club) with their birds because they are fully aware of their birds' flight status. Another thing to remember about fully flighted birds versus clipped birds who have gotten outside is that their chances of survival are much better because they are less apt to become dinner to a predictor since their primary form of escape is still in tact. This also means their chance of returning to you is much better.
