This guide pairs familiar names with anatomical terms and shows how the skeleton, organs, muscles, skin and senses fit together. It explains normal anatomy, not how to diagnose or treat a health problem.
How to read a cat anatomy diagram
Start with the body regions, then follow the systems that cross them. The skeleton provides support and movement; the skin and coat cover and protect the body; and organs in the chest and abdomen carry out functions such as breathing, circulation and digestion. Nerves link the brain and spinal cord to the rest of the body, while sensory organs provide sight, hearing, smell, taste and touch.
For a simple front-to-back orientation, the head joins the neck, which leads into the thorax (chest). The abdomen lies behind the diaphragm, and the pelvis sits at the rear of the trunk. Forelimbs attach near the shoulders; hindlimbs connect at the pelvis. The tail continues the vertebral column. Veterinary atlases commonly organize anatomy both by region and by organ system, because structures in one area often belong to different systems.
What are the parts of a cat’s skin and coat?
The integumentary system includes the skin, hair and associated structures. Skin is a protective organ with an outer epidermis and an underlying dermis. Hair grows from follicles in the skin; sebaceous glands associated with follicles produce oily secretions that help coat the hair and skin.
#1 Best Overall
Washington State’s introductory educational anatomy document says sweat glands are located on cats’ foot pads. Its discussion is a general anatomy overview, not treatment guidance. Because substances applied to a cat’s skin may be absorbed, ask a veterinarian before using topical medication or other products.
What is a cat’s skeleton called, and how is it arranged?
A cat’s skeleton is its bony framework. The axial skeleton runs along the body’s central axis and includes the skull, vertebral column, ribs and sternum. The appendicular skeleton includes the bones of the forelimbs and hindlimbs. Joints connect bones; cartilage cushions or covers surfaces at some joints, ligaments connect bone to bone, and tendons attach muscle to bone.
Rank #2
According to the Washington State educational document (publication date not stated), cats have 230 bones, 13 pairs of ribs, and a spine divided into cervical, thoracic, lumbar, sacral and caudal regions. It lists seven cervical, 13 thoracic and seven lumbar vertebrae, three fused sacral vertebrae, and usually 18–23 caudal vertebrae. These are source-attributed reference counts, not a guarantee that every cat has an identical skeleton; tail vertebrae in particular vary.
The document also notes that cats have clavicles (collarbones), but these are not attached to other bones. This differs from a rigid bony connection between the forelimbs and trunk and is one feature of the cat’s flexible skeletal arrangement.

- Carpus: wrist.
- Metacarpus: palm portion of the paw, between wrist and digits.
- Phalanges: digit bones, including those in the toes.
Hindlimb: hip to toes
- Pelvis: bony structure connecting the hindlimbs to the trunk.
- Femur: thigh bone.
- Patella: kneecap, at the stifle (knee).
- Tibia and fibula: lower hindlimb bones.
- Tarsus: hock, the joint region above the hind paw.
- Metatarsus: the portion of the hind paw between hock and digits.
- Phalanges: bones of the toes.
How joints and muscles produce movement
Muscles contract and pull on tendons, which move bones across joints. The Washington State document uses a simplified teaching description: shoulder and hip joints are ball-and-socket joints, while other joints are described as hinge-type. That is a useful introductory picture, not a complete account of every joint’s movement. A labeled osteology atlas can help locate structures such as the shoulder, elbow, knee and pelvic joints.
How many teeth do cats have?
The Washington State educational document (publication date not stated) gives an adult cat’s count as 30 teeth: 12 incisors, four canines, 10 premolars and four molars. It lists 26 deciduous (baby) teeth in kittens, with no molars. These figures describe the source’s general anatomy overview; this section is not dental-care advice.
Where are a cat’s organs?
The thorax contains the heart and lungs. The diaphragm is a muscular partition between the chest cavity and the abdominal cavity. Behind it, the abdomen contains much of the digestive system and urinary organs; the pelvic region contains additional urinary and reproductive structures. Exact positions and appearances are best studied in a labeled anatomical illustration or imaging reference rather than inferred from an external view.
Organs belong to systems that extend across regions. The digestive system processes food; the cardiovascular system includes the heart and blood vessels; the respiratory system includes the lungs and airways; and the urogenital system encompasses urinary and reproductive structures. Regional imaging references group views of the thorax and abdomen-pelvis to help orient readers to those internal areas.
How do the brain, nerves and senses fit in?
The nervous system includes the brain in the skull, the spinal cord within the vertebral column, and peripheral nerves branching through the body. These structures link the central nervous system with limbs, organs and sensory pathways. Special sensory organs are covered as a distinct topic in feline anatomy references; they should not be confused with the general anatomy of the head and neck.
Which cat anatomy atlas should you use?
Choose a reference based on whether you need a general labeled overview, a feline-specific professional resource, or examples of normal anatomy in medical images. Osteology illustrations show bones and joints; radiographs show how normal structures appear in X-rays. Neither an atlas nor a normal reference image interprets an individual cat’s scan.
- Feline-specific system reference: Lola Hudson and William Hamilton’s Atlas of Feline Anatomy for Veterinarians, second edition, is described by Routledge as containing more than 266 full-color drawings organized by organ system and focused on anatomy encountered in clinical practice. It is aimed at veterinary learners and professionals.
- Dog-and-cat clinical atlas: Jack S. Boyd and Callum Paterson’s Colour Atlas of Clinical Anatomy of the Dog and Cat, second edition is listed by Elsevier with a 2000 publication date. The publisher describes more than 300 color photographs of fresh dissections, plus more than 100 radiographs, ultrasound scans, CT images and diagrams. It covers both species and uses clinical as well as regional material.
- Digital skeletal atlas: IMAIOS vet-Anatomy’s feline osteology module reports 163 original medical illustrations covering the skull, vertebral column, thorax and limbs, and follows Nomina Anatomica Veterinaria, Sixth Edition (2017). Its page was published February 24, 2026, and updated August 6, 2026.
- Digital normal radiographs: IMAIOS’s feline X-ray atlas describes 39 sampled X-ray images of healthy cats grouped into head, vertebral column, thoracic limb, pelvic limb, thorax and abdomen-pelvis. The page was published June 17, 2019, and updated August 6, 2026. The atlas presents normal imaging for orientation; a veterinarian must interpret an individual animal’s images.
For a visual introduction, look for labels that pair anatomical names with everyday terms and show both the body region and the system. For clinical study, compare the edition and coverage: the feline-only atlas is organized by organ system, while the dog-and-cat atlas offers dissection photographs and multiple imaging types. Digital atlas access and current availability can change, so check the linked listing for its present terms.
