es will do.

In the winter not so much ventilation is needed.

For food use plenty of hay together with some green food or carrots,
beets, etc. No water is necessary. Do not ship out during a real cold
spell in winter or a real hot spell in summer.

Do not have your box larger than necessary as it means added weight and
at the same time do not have it so small that they are crowded all over
each other.

CHAPTER IX

DISEASES.

Guinea Pigs are singularly free from disease and the breeder has little
to fear along this line. Of course improper food, irregular feeding
hours, poorly ventilated or exposed quarters will often cause trouble
but it is almost an unknown thing for an epidemic to get in a herd and
kill them off. As long as they are fed judiciously and their quarters
are kept sweet and clean and well protected from wind, rain and snow,
you will have little trouble. They are remarkably healthy little animals
but of course will not stand neglect or improper care. Do your share and
you will but seldom lose a Cavy.

Diarrhoea.

This is one of the most common troubles that a Cavy raiser has to
contend with. Too much green food, mouldy and half cured hay and a
sudden change of food is usually the cause. Give them plenty of good
sweet hay and cut out the green food for a while. A small spoon of olive
oil or a little castor oil is good to clean out the bowels.

Constipation.

Caused by not enough green food. This trouble is not apt to occur except
in winter when greens are scarce. Give them apple parings, any green
stuff you can get and a little olive oil. Always try and feed at least
once a day a little green stuff and you will have no trouble.

Premature Birth.

Females are occasionally lost when giving birth prematurely to little
ones and sometimes the young ones when born are so weak that they do not
live long. This is caused by too frequent littering, by fright, over
fatness or physical weakness. Over crowding in a cold drafty hutch in
severe weather may so weaken the mother that she bears weak ones. Take
especially good care of the pregnant females. Give them the choice food
and the best quarters. Do not let them breed too often or start too
young. Do not allow them to be handled or frightened.

Worms.

If a Guinea Pig is a good feeder and still does not grow, if he looks
unhealthy and his coat is not glossy he may have worms. Give a half
teaspoonful of any kind of worm medicine such
