I can understand your point of view, but what I can't do is speak for the owner of the cat, I can only make assumptions by observation which may be right or wrong as I don't have all of the facts.
As to why they chose to film it I wouldn't know myself if it was just to show their friend what their cat kept doing, then they, or someone else who had a copy of it decided to uploaded it, or if it was purely to gain points on the internet, which of course if so would be rather sad.
But I'd like to think that they just filmed their cat for once doing what it did and then the upload decision came later, unless you know otherwise for certain, having spoken with the cats owner.
For all I know they may have tried to stop the cat from doing that many times before, but I just don't know.
Thanks for the feedback though.
It's a shame that I can't private message you on here rather than fill up this space with a long discussion, but that would also make the site more complicated to run.
