Why dissect a cat?
Computer-assisted learning and the use of plastinated specimens can supplement dissection, but they cannot give a complete idea of
what an organ or organ system is really like. Dissection is the best way for students to obtain knowledge of tissue
characteristics, such as strength, composition, color, and texture and to understand the
3-dimensional relationships of organs
and organ systems.
One of the best specimens to use for exploring mammalian anatomy is the cat. It is large enough for its internal organs (which are much
like our own) to be found easily and for its blood vessels to be traced, but not so large as to present special difficulty in storage
and handling. Preserved cat specimens are also reasonably priced and readily available.
How does Carolina obtain its cats?
Animal shelters licensed by the US Department of Agriculture (USDA) supply us with euthanized cats that would otherwise be destined
for the landfills were they not reutilized for science classrooms. The USDA, under the Animal Welfare Act, governs the procurement of
animals. Carolina is proud to have an outstanding USDA inspection and compliance record, and we are committed to treating all animals
in a humane manner.
Getting started: External anatomy
Explore your specimen’s external anatomy using the following procedure.
- Don lab apron or coat, gloves, and eye protection.
- Place the specimen in a dissecting tray and identify features that are similar to and different from human features.
- Locate and examine the following structures:
- Head, including eyes and eyelids; pinnae (external ear structures); mouth; nares (nostrils); philtrum (cleft in
upper lip); and vibrissae (long, stiff hairs around the mouth, cheeks, and eyes)
- Neck
- Trunk, including mammillary papillae (teats); anus; urogenital opening or scrotum and penis; and tail
- Forelimbs, including shoulders; elbows; wrists; feet; toes; claws; and tori (foot pads)
- Hind limbs, including hips; knees; ankles; feet; toes; claws; and tori (foot pads)
- Separate the upper and lower eyelids. Locate and examine the third eyelid, the nictitating membrane.
- Return the specimen to storage or proceed with internal dissection as your instructor directs.
