I’ve watched this gif over and over, and I think this is what’s going on: The cat was trying to jump on the bed, but it was sitting on a magazine (as cats do) and the magazine slipped which messed up it’s jump. Then it tried to claw onto the bed sheets which is why it gets all stiff at the end. I’m sure the cat’s owner ran over and helped it right after this clip was taken. But I can’t help but giggle. Cats! Why do you do stuff like this!
