How many vertebrae are found in the lumbar spine of cats and dogs?

Explanation:
Seven vertebrae make up the lumbar spine in cats and dogs. The lumbar region sits between the last thoracic vertebrae (which bear ribs) and the first sacral vertebrae. In domestic dogs and cats, the typical vertebral formula is C7 T13 L7 S3, so the lumbar section consists of seven vertebrae. This consistent count helps with locating spinal levels on radiographs and planning procedures. While humans commonly have five lumbar vertebrae, and occasional anatomical variations can occur, seven is the normal number for these species.
