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 analyzing of serums and antitoxins 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 assured 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 assured 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.
