(ruiuea pig pens may be kept outside in a mild 

 climate. In most areas, they need to be in a heated 

 building, (luinea pigs do not thrive at temperatures 

 below 65° F. 



The pens need not be elaborate because guinea 

 pigs usually do not climb, jump, or gnaw on wood. 

 However, most pens do have some sort of screen 

 wire or hardware cloth across the top. The sides 

 may also be made of screen. 



Provide a shelf about 4 inches off the floor in a 

 dark corner of the cage. Females and their litters 

 Avill seek shelter under the shelf, (luinea pigs like 

 t o sleep on a shelf. 



Cover the pen floors with wood shavings or straw to 

 absorb moisture. Clean the pen floors at least once 

 a week. 



A pen 80 by 86 inches and 12 to 15 inches high is 

 large enough for a male and 5 or 6 breeding females. 

 A larger pen, 5 by 10 feet, can accommodate 30 to 50 

 guinea pigs.
