How Big of A Cage Does a Guinea Pig Need? [&Why It Matters]

HomeCareHow Big of A Cage Does a Guinea Pig Need?

Guinea pigs require a minimum of 7.5 square feet of floor space in their cage, with a minimum height of 12 inches. The ideal size cage for guinea pigs is anywhere from 10-15 square feet, with a minimum height of 18 inches. The taller the cage, the better, as it allows for more space for the guinea pig to explore.

When considering the size of their cage, guinea pigs should also have access to multiple levels. This could be achieved by providing a ramp leading to a platform, or two platforms at different heights. This allows for a more stimulating environment that encourages the guinea pig to stay active.

Wire or plastic cages with solid floors and ramps are the best choice for guinea pigs. This type of cage is important because it allows for proper ventilation, which is essential for guinea pigs. It also helps to prevent any accidents or falls while they are exploring.

When setting up the cage, there are certain accessories that should be included. These include a water bottle, a hay feeder, a solid ramp, and a hideout. All of these items should be placed in different areas of the cage, as this will create a stimulating environment for the guinea pig.

How To Measure A Guinea Pig Cage

When purchasing a new guinea pig cage, the box should tell you how big the cage is. However, if you’re purchasing a used cage, you may not know the exact dimensions.

The best way to measure a guinea pig cage is to use a tape measure. Start by measuring the length and width of the cage, then measure the height of the walls and the distance between the bars. Finally, measure the space between the floor and the base of the cage. This will give you an accurate measurement of the size of the cage.

How Can You Make Sure Your Guinea Pig Has Enough Space?

A big part of organizing a guinea pigs cage will depend on the size and shape of the cage. It’s best to start with a list of items you need and then you can determine where to put them to maximize space.

Below is a list of essential items. For some of these items, we gave recommendations for where to put them.

Comfortable Bedding Material

Choose a bedding material such as untreated wood shavings, paper-based bedding, or hay.


Guinea pigs like to hide and feel secure, so provide multiple hiding spots. Cardboard boxes, tunnels, and other hideaways are great options.

Litter Box (If You Want to Litter Train)

Place a litter box in one corner of the cage and fill it with a guinea pig-safe litter material.

Food Dish

Place a heavy-duty food dish in the cage and fill it with guinea pig-safe food.

Water Bottle

Attach a water bottle to the side of the cage and fill it with fresh, clean water.


Guinea pigs need mental stimulation, so include toys and other enrichment items in the cage.

With those items in mind, you should be able to map out your guinea pigs cage to maximize the space.

Ways To Tell If The Cage Is Big Enough For Your Guinea Pig

Unfortunately, many guinea pig owners end up with cages that are too small for their pet. But how do you know if the cage is too small for your guinea pig?

Watch Their Behavior

The easiest way to tell if a cage is too small is to observe the guinea pig’s behavior. If the guinea pig is constantly biting at the bars, trying to escape, or displaying other signs of stress, then the cage may be too small.

Are They Over-Grooming?

If the guinea pig is exhibiting signs of aggression or over-grooming, then it may be a sign that it’s feeling cramped and uncomfortable.

The Bedding is Constantly Soiled

Guinea pigs require enough space to use separate areas for their litter boxes and eating. If there isn’t enough room for this, then it’s likely the cage is too small.

It’s important to pay attention to these signs in order to ensure that your guinea pig has a healthy and comfortable living space. If you think your guinea pig’s cage is too small, then it’s best to upgrade to a larger one as soon as possible.

Why Bigger Is Better When It Comes To Guinea Pig Cages

More Stimulating Environment

When it comes to guinea pig cages, bigger is always better. Bigger cages give guinea pigs more space to move around and explore, as well as providing a more stimulating environment. A larger cage also allows for more enrichment and interactive toys, which provides important mental stimulation for guinea pigs and encourages them to be active.

More Comfort

Larger cages are also more comfortable for guinea pigs as they provide them with more space to stretch and move around. Guinea pigs can get frustrated and anxious if they feel cramped or unable to explore their environment, but with a larger cage, they have plenty of space to move around and explore.


A larger cage is a safer option for guinea pigs. Small cages can be difficult to clean and maintain, making them a potential source of illness or injury for guinea pigs. Bigger cages are easier to clean, and make it easier to provide guinea pigs with a safe, healthy environment.
