OMG, these videos DO make me feel very sad.... . My sweety Inka has CH too. Luckily she has a mild version. She can walk without falling, but as soon as she starts running, her she makes one salto after another. She cannot guess distances and has almost no balance, poor cat. She is also very insecure and gets startled by the slightest movement or noise . I don't have videos showing this, I will try to make them in the future. Inka is now 4 1/2 years old. She loves to jump on my bed and rest on my shoulder or tummy; but when she jumps she only uses her hint legs (looks like a kangaroo then), and doesn't know where and how she will touch down... . Mostly she jumps too far, slides to the edge of the bed, and falls down on the floor
Here she is, my gorgeous cat Inka:






I love her immensely, she is very special little princess
