How does his body feel? because they are all a little different in size and structure, it is best to go by feel, when you put your hands on him can you still feel his structure underneath? You should be able to feel his bones but they should not be obvious or sticking out.
It does concern me that he is still getting shaky between meals though. Have you had any blood work done on him?
