Heres Sobeks uncle Shadow, he was deformed at hatching, his backbone had a sharp fold in it, and his ribs overlapped. The more he grew the more he got worse, when he grew to over 4ft 2 inches his deformity became to much for his body and the fold in his spine led to his death.
From the outside it never looked that bad until you saw the X-ray.

He was a sweetheart, so calm, interesting attitude, a bit hissy sometimes, but he loved women, he would climb on their laps and hang on tight putting up with almost anything, that and sometimes evert and mark them, lol.
