Overview of Small Animal Science
Objectives
Define the terms ‘Zoology’ and ‘Zoonosis’
Sort different small animal species into their
designated taxonomic groups
Identify the different small animal categories
that are used for this class
Analyze the different animal taxonomy groups
The study of animals is called zoology
...
Animal scientists are called zoologists.
Animals are classified into different groups for
study.
Animals are generally classified like
this ...
Kingdom
Phylum
Class
Order
Family
Genus
Species
More general
More specific
This classification system is a
taxonomy ...
Taxonomy is the branch of science concerned
with the classification of organisms.
The animal must meet all the requirements
starting from the highest category -- the
KINGDOM
Down to the lowest category to fit into a
particular group -- in this case, the SPECIE
All animals in these lessons fit in 5
categories:
Osteichthyes (bony fishes)
Amphibia or amphibians (frogs and toads)
Reptilia or reptiles (snakes and lizards)
Aves/Aviary (birds)
Mammalia or mammals (dogs, cats and rabbits)
The study of fish ...
Is called icthyology
Subphylum: Pisces
Live in water
Permanent gills for
breathing, fins and body
covered with scales
Cold-blooded
The study of amphibians ...
Is called herpetology
Cold-blooded
vertebrates
Young live in water,
while
adults live on land.
Includes frogs, toads,
newts, salamanders

The study of reptiles ...
Is also called
herpetology
Cold-blooded

Lungs, bony skeleton
Body covered with scales or horny plates
Heart with 2 atria and 1 ventricle
Snakes, lizards, crocodiles, alligators, turtles,
tortoises, dinosaurs
The study of birds ...
Is called ornithology
Includes poultry
Warm-blooded
Two legs, wings,
feathers
Lay eggs
The study of mammals ...
 Is called mammalogy
 Feed their young
with milk from the
mother's body
 Skin is more or less
covered with hair
 Considered the
highest form of life

Examples of mammals ...
Humans
Non-human primates
Dogs, cats, rabbits, mice, rats, guinea pigs,
chinchillas, ferrets, cows, pigs, goats, sheep,
horses
Marine mammals like dolphins, whales
Marsupials like kangaroos, possums
Flying mammals like bats
How are small animals used?
Companion animals and pets
Food or hide
• Rabbits, mink
• Frogs, alligators
Research
• Nonhuman primates
• Dogs, cats, rabbits
• Rats, mice
Animal welfare vs. Animal Rights
Animal Welfare:
Animal Rights:
 Animals should be
treated humanely.
 Animals can be used for
human purposes.
 Animals have the same
rights as humans.
 Animals should not be
used for food, clothing,
entertainment or
research.
 Ethically wrong for
animals to be used for
human purposes.
Animal Welfare Act of 1966
Regulates dealers and laboratories
Mandates standards for housing, handling,
treatment, feeding and shelter of laboratory
animals
Research institutions must have a review
committee
Procedures for euthanasia
Risks in working with animals ...
Zoonosis (disease that can be transmitted
from animal to human)
•

Internal parasites
Toxoplasmosis
Rabies
Bacteria

Overview of the industry:
Companion animal industry is big and growing
bigger
Cats and dogs have largest share
Consumers spend a lot on their pets:
•
•
•
•
Pet food (about 47% of spending)
Health services
Toys, collars, leashes, etc.
Grooming, boarding, training, breeding, etc.
