A. Little is known for certain about how guinea pigs were first introduced
to Europe and North America as a domestic pet, but they most probably
came during the 16th century. Holland, Portugal and Spain had colonies
in South America, and the explorers brought to Europe gold and precious
gems, along with other unusual and exciting finds. Colourful parrots
became very popular status symbols in the homes of the wealthy,
and with them came the guinea pig and other animals previously
unknown in Europe.
B. Many species of wild animals are in danger of complete extinction. This
is usually due to loss of habitat as a result of human expansion, or it
could be due to excessive hunting. A_ good, modern zoo has a valuable
role to play in assisting with the protection of endangered species. This
is both through education of the general public in the importance of
conservation in general and through breeding programmes to increase
the population of endangered species in captivity and then reintroduce
them into the wild.
C. The guinea pig is today one of the world’s most popular pets, ranking
only a little way behind the rabbit. Though called guinea pigs, these
animals are not pigs, nor do they come from Guinea. Why Guinea then?
Some say they could have originally changed hands at the cost of a
guinea (twenty-one shillings – very expensive they were!). As for the
“pig”, an explanation is much easier to guess – they run and squeal much
as little piglets do!
D. Rabbits are one of the most popular pets to keep due to their affectionate
nature and love of cuddles. To show they are happy, they often grind
their teeth softly when being petted, similar to cats purring. In general,
rabbits are timid and non-aggressive and sociable with each other. With
gentle handling they are generally quite tame. They are playful and
entertaining to watch, but they need a great deal of interaction with
their owners. Their cage should be relatively big, but they need some
playtime outside it as well.
E. For a long time guinea pigs were used as experimental animals. In
1890, the antitoxin for diphtheria was discovered using guinea pigs
in the research, and as a result, the lives of millions of children have
been saved. In 1907, vitamin C was discovered due to guinea pigs. Like
humans they cannot produce the vitamin and need it supplied in their
diet. The guinea pig’s wide variety of hair types and colours has also
made them a prime choice for studies of genetics and heredity. Later,
they have been replaced by rats and mice.
F. Security at Denver International Airport tries to protect cars from vandalism
and theft, but there’s a new threat at its expansive parking lot.
Ravenous rabbits. The animals are causing hundreds and sometimes
thousands of dollars in damage to cars by devouring the wires under the
hood. At least 100 rabbits are removed every month, but the problem
persists. The airport is surrounded by prairie, and the rabbits are seeking
warmth and food in the parked vehicles.
G. Our mission at Wild Adventures Zoo is to bring family entertainment
back to Las Vegas, in an educational manner. Teaching respect for
animals through hands on applications, workshops and conservation
efforts, as well as helping injured and abandoned wildlife and exotic
pets, is the reason Wild Adventures Zoo was created. Our focus is on
educating the public through fun and exciting activities that allow them
to interact with the animals.
