In this Xray Pictures we can see the skeleton of the cat and it's internal organs...
AWESOME!!! Thank you -" NudiePatooties " and thank you Wilhelm Conrad Röntgen.
The basic anatomy of skeleton relate to the presence of seven cervical vertebrae, five lumbar vertebrae, twelve thoracic vertebrae, five sacral vertebrae and one to four coccygeal vertebrae.
The connection between the cat's vertebras is looser than human's vertebras connection.
It makes the cat's spinal column very pliable.
That's how the cat can make a "n" shape with his spinal column.
