When our cat was pregnant, she was counterbalanced in a way that when she tried to lie down on our side so we could pet her she ended up accidentally rolling completely over and winding up standing again.
I agree with the assessments here, but the cat actually getting up and moving around is... pretty horrifying. I guess I've taken on an unintentional task of finding uncute cat movies to offset the millions of cat videos which I feel compelled to five star like they were injecting liquid valium straight into my eyes.
