Sorry to hear this. I had a friend with a kitten that an adult cat jumped on playing too roughly and broke its leg or may have been similar to your kitty's problem, the kit had to have the leg amputated. That is worse case scenario for you but hopefully it will not come to anything like that. If it does its amazing how they adapt to it and the cat as an adult is still right as rain. On the other hand your kit may not need this and all being well the leg will heal just fine on its own. Good luck for you both. Cx.
