The Bigger the cage, The better!
Cramped cages means dull lives for the inhabitants, and dull pets for their keeper. Many commercially produced hutches are too small and amount to prison cells rather than homes. To ensure that your pets have room to move, allow 65sq cm (7sq ft) for one guinea pig, adding about 20sq cm (2sq ft) for each additional animal.
The hutch should have a smooth floor (not wire base), and should have one end partitioned off to provide secluded sleeping quarters. Never placed a hutch directly on the ground, but raise it on legs so that air circulates beneath, protecting both hutch and guinea pig from damp. Outdoor hutches need weather-proofing, using non-toxic wood preservatives, and a sloping roof to let rain drain off.
A HOME INDOORS
Indoor cages are usually made of plastic for ease of cleaning, with a deep tray base to prevent spillage of bedding. They may be sold as complete kits with food bowl, water bottle and hay rack, or you may need to buy these separately.
Pick the largest cage you can accomodate, as some are too small to be kind. Plastic cages rarely offer the occupant any privacy, so add a hideaway nestbox to make your pet more comfortable.
If you choose to locate your pet’s cage indoors, choose the site carefully. The noisest, busiest room in the house may be too stressful, while an out-of-the-way corner may lead to neglect. It is important to avoid draughts, direct sunlight and dramatic changes in temperature!
A comfortable living-room temperature for humans suits guinea pigs just as well. Placing the cage on a sturdy table or stand makes access easier, avoid draught, and means that you won’t loom threateningly over your pet when you approach.
