This video is about Speedo, our loving and adorable foster kitten, and his 'Road through Rehabilitation.' Here he uses his "Alley," which is narrow enough to prevent him from splaying his legs outward, thus forcing him to use and strengthen the muscles he needs in order to be able to stand upright.

In the second clip you can see his legs from behind...during the first week his legs would still go up and out when walking through his Alley even with the tape on, but here you can see how much he has improved so far and how he now has the ability to remain upright and really exercise those muscles :)
