So the cats, clearly untrained and not expecting sudden zero G, improvised reasonably well. They didn't land on their feet, but they did not land anywhere else, either, and it did not look like they were given a lot of opportunity to learn. The video did not follow the conclusion of the zero G period and the resumption of normal gravity, which would have let them land and actually answered the question. It'll take a few more rides on the Vomit Comet to work out what there is to know, though honestly given the entirely questionable scientific impact, you have to ask yourself does this cross the line into animal cruelty?
