Hi Katie
I've only just seen this post so I hope if your kitten wasn't getting better you have now managed to take her for a check up. Your thinking was correct that you needed to make sure she hadn't broken her tail or done some damage to her pelvis and the nerve supply to her bowels and bladder control which runs in the lower spine. I hope that the fall wasn't too far and that nothing that bad has happened.
