The Raising and Care of Guinea Pigs.
by A. C. Smith.
CHAPTER I
INTRODUCTION.
The Guinea Pig or Cavy belongs to the rabbit family and is a native of South America. Why they are called Guinea Pigs, no one seems to know, unless their shape suggests a small pig and the name Guinea is a corruption of Guiana, a country in South America. In size, shape and texture of fur they resemble a squirrel or rabbit. They have large bodies, short legs, small feet, no tails and a wide range of colors. A full grown Cavy weighs between two and three pounds, which weight it attains at about 18 months of age. The males are usually larger than the females.
When white people first visited the Andean region of South America they found the Cavy domesticated and living in the houses of the Indians, by whom they were used for food. They were introduced into Europe in the 16th Century and since that time have spread all over the world. In South America there are still several species of wild Cavies. These are hunted as game and are considered a great delicacy.
Cavies are wholly vegetarian in diet, eating about the same things as a rabbit. They are very easily tamed, are very healthy and hardy, are not noisy, are clean in their habits, and have no offensive odor. There is probably no animal in the world that is easier to handle. They easily adapt themselves to conditions and seem to do equally as well in city or country, in large or small quarters and a few of them together do as well as a large number of them.
They are practically free from the diseases and epidemics that make the raising of poultry and rabbits so uncertain. Some of them get sick and die, of course, but it is usually due to some local cause or to the fact that they have been neglected or improperly fed or housed, but contagious diseases such as will often wipe out whole flocks of poultry or a pen of rabbits are unknown among Cavies.
All of these things make the raising of Guinea Pigs a very pleasant as well as a very profitable occupation.
CHAPTER II
VARIETIES.
English.
There are several varieties of Cavies, distinguished mainly by their fur. The ones most commonly raised and most widely known are the English or smooth-haired. These are the ones you should raise for commercial purposes. They may be in color: white, black, red, fawn, cream, gray, brindle, brown, or a mixture of these colors. The whites are usually albinos and have pink eyes.

Peruvian.
The Peruvian has long silken hair and may be called the aristocrat of Cavydom. They are raised princ.i.p.ally by fanciers and for general purposes are no more valuable than the short haired ones, are not as hardy and are more trouble to handle as their coat needs careful attention.
Abyssinian.
This, like the Peruvian, is also a fancy breed. It has longer hair than the short-haired, and it stands out in curious little rosettes. These are more hardy than the Peruvian and are more common.
The Kind to Raise.
If you expect to raise Cavies for commercial purposes the English is the kind that should pay you best. They are easier to take care of than the long-haired varieties. For laboratories, experimental purposes, etc., it is the smooth-haired Cavy that is in most demand. If you are a Guinea Pig fancier or are raising them for pet purposes it is merely a matter of taste and choice. The long-haired ones are usually more expensive and sell for more, as they are scarcer and are generally sold for pet and fancy purposes. It is usually well to have a few Abyssinian among your stock if you are raising many, as many people prefer them for pets.
CHAPTER III
USES OF GUINEA PIGS.
There are three main uses to which Guinea Pigs are put, as food, as pets and for experimental purposes in laboratory and medical research. By far the largest demand is in the last named field.
Scientific Uses.
There is possibly no animal so well adapted for scientific experiments as the Guinea Pig. In the testing and a.n.a.lyzing of serums and ant.i.toxins and for experimental purposes generally the demand is enormous, thousands and thousands of them being used every year. Many of the large hospitals and laboratories have been compelled to establish breeding pens of their own in order to be sure of a constant supply. The demand here is steadily increasing and many more would be used if they could be obtained at a reasonable price. A United States Bulletin says, "Guinea Pigs sell at various prices dependant on supply and demand. The average price for several years has been about 75c, but laboratories now report that suitable stock is short and that they have been paying from $1.00 to $1.50 for their supply of animals." For these purposes they are used all the way from nine weeks to six months or more old or when they weigh from 9 ounces and up. The cost of rearing them to this age is very little and a good profit is therefore a.s.sured the raiser.
As Pets.
The demand for Guinea Pigs as pets is very large. They are so widely used in the medical field that the pet stores have a hard time keeping enough on hand to supply the local demand for pets. They are very interesting and perfectly harmless little animals. They do not bite or scratch and young children can play with them. They are not as common as the ordinary pet, and being more of a novelty, attract more attention.
When sold as pets they usually bring more than when sold to the hospitals and raisers are a.s.sured of a very large demand for this purpose. In England and Europe the Guinea Pig is more widely raised than in America and there are more fanciers who show and exhibit them extensively. They are becoming more popular in this country and are being exhibited more and more in Pet Stock Shows. A good show animal is worth all the way from $10 to $100. As a hobby the raising of Guinea Pigs is most interesting and instructive as there are so many experiments that can be made in the breeding.
As Food.
For food purposes Guinea Pigs are admirable, although not many are eaten in this country at the present time. However, many of the newspapers and magazines have run articles suggesting that they be raised for this purpose and there is really no reason why they should not be. The United States Government indorses them as food animals and advises that they be used in this connection. In a few years we will possibly see Guinea Pigs sold in the stores as rabbits and poultry are now. Certainly no animal could be cleaner and being a vegetarian exclusively, its flesh is of the best. They can be prepared just as a rabbit or squirrel. In soups, stews, pies, or roasted, broiled or baked the young Cavy is equal to any other animal. For this purpose the animal should be about one-half grown.

CHAPTER IV
FOOD AND FEEDING.
The feeding of Guinea Pigs is a very simple matter. Their main food is good hay or dried gra.s.s. This should be before them all the time, as they will not eat too much of it. Be sure, however, that it is not musty or mouldy.
In addition to hay, they should have at least once a day, a feeding of green food. This is essential in keeping them from becoming constipated.
By green food we mean such things as lawn clippings, green clover, spinach, green corn stalks, lettuce, celery tops, plantain, dandelion, gra.s.ses, etc., which is, of course, very plentiful in the summer. In the winter when you cannot get these, carrots, beets, apples, cabbage, mangle beets, yellow turnips, etc., will take their place.
The grains such as oats, wheat, corn, bran, chops, etc., should be fed them, as it makes flesh and gives them strength. Oats is probably the best of them all. Stale bread is also good, but it should not be greasy or mouldy. A good plan is to feed in the morning hay and grain or a bran or chops mash instead of the grain. At noon some green stuff or roots and at night hay. Give them all the hay they can eat. Keep it before them all of the time, but only feed as much green stuff as they can clear up in a few hours. They are also not apt to overeat grain, which should be fed in an earthen or wooden vessel. If you feed only twice a day, give them the green food in the morning with the hay. Guinea Pigs drink but little water when eating green food, but they should have a vessel of fresh water in the hutch or pen every morning. It is also well to keep a piece of rock salt in each hutch.
In the spring or summer you can feed more green stuff than in the winter, in fact, we have raised them in the summer on an exclusive green food diet by moving the hutches from place to place on the lawn. But in the winter and fall, when greens are scarce and they are not used to them, a sudden over-feeding might result in severe loss. Avoid a sudden change of diet.
In the spring and summer there is but little food to buy for them. Even the city raiser, by saving his own and his neighbors" lawn clippings, can be well supplied. By curing these clippings a good grade of hay is obtained. A little grain, especially for the pregnant mothers, is all that need be bought.
Bread and milk is a good flesh producer and should be fed any weak ones, also nursing mothers. In the winter it should be warmed.
The feeding of Cavies, you see, is a very simple matter, even for a city man. The commission houses every day throw away enough lettuce, cabbage, celery, etc., to feed a large number. Stale bread can always be bought very cheaply from the bakeries. On the farm nothing whatever need be bought at any time.
