The person who made that video made it on purpose...as in, they knew their cat would run into the glass. Not very nice of them. Technically, that is animal abuse. Making a video just for internet views is okay, unless you do something immoral or unethical to make it.
If they were throwing the cat in to the glass then you could call it animal abuse but filming it once doing what it does can hardly be considered animal abuse, I guess they could buy him a crash helmet but calling them animal abusers just because they filmed it isn't going to stop the cat from doing it again, maybe it will learn one day maybe it won't but that is typically how we all learn certain things.
I saw my own cat trying to walk over a flip top bin once so I checked that there was nothing in it that could hurt her before I let her fall in, why.. because if she hadn't learnt that day then she would of just done it another day, quite possibly when I was out and then she would of been stuck inside the bin for hours, she never did it again but she did need to learn the lesson as saying no sometimes is just not enough.
I agree with most of what you said, but the owner knew what would happen, and they did it so they could record it on video and then win internet points with the video of their cat crashing into a glass door. Most pet owners would not do that. Why? Because it is mean. The cat had likely done it numerous times before and was clearly not learning anything. It may not be animal abuse, but it sure does border on it.
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.
