Can Guinea Pigs Live Outside? (Temperature, Security & Other Concerns)

Genevieve Dugal

Guinea pig owners may sometimes wonder if they can put their small animals outside. Is it possible? Under what conditions? Are there any risks?

The short answer is yes, guinea pigs can live outside, but under certain conditions. If you have a fenced garden or a protected balcony, you can regularly take your guinea pig outdoors. You can even set up a permanent cage outside, especially if you have several of these friendly, gregarious little rodents. There are of course certain precautions to follow, since being outside, your little furry companion will be more exposed to the whims of Mother Nature, as well as to potential predators.divider-guineapig

What You Should Know Before Moving Your Guinea Pig Outside

You may have in mind the image of South American guinea pigs living free and running happily in the fields. Although your little guinea pig is of the same species, you should know that it was domesticated around 6,000 years ago. Therefore, significant morphological and physiological changes have taken place: your pet guinea pig is no longer as robust as its cousin from South America.

Thus, leaving your guinea pig roaming alone in your garden under the pretext of offering him some freedom is therefore irresponsible because the dangers are numerous for your small and gentle rodent. Indeed, guinea pigs need attention, contact with their human or their congeners, and stimulation to thrive. Therefore, life outside will require some adaptation; first of all, against the cold, predators, and …boredom!

What Temperature Can Guinea Pigs Stay Outside?

Guinea pigs can survive outside temperatures between 64°F and 73°F. On the other hand, if you live in places where the temperatures drop below 59°F or exceed 79°F, building a suitable outdoor shelter for your guinea pig will be better, especially if you plan to leave it outdoors all year long. In any case, use common sense and bring your little rodent inside your house if the weather conditions become dangerous for him.

Can Guineas Pigs Stay Outside in Winter?

Yes, guinea pigs can live outdoors year-round. However, if you decide to let your pet outside during the winter, you need to ensure that its enclosure is protected from cold, wind, and rain.divider-guineapig

How To Make an Outdoor Cage for Your Guinea Pig

Although many owners use cages purchased from pet stores, they are often too small and do not provide the space that guinea pigs need. They will be happier and healthier if you can give them a large, exciting environment with enough space to explore. Whether you keep yours indoors or outdoors, there are plenty of options to give your little rodent a comfortable living space.

1. Design a Plan of the Outdoor Cage

The outdoor guinea pig cage should be sturdy. Designing the enclosure is the first step in preparing it. How big should you give it? Well, as a general rule, the bigger it is, the better. Guinea pigs need at least two square meters of space; if you have two animals, three square meters should be fine. You can also design a tiered cage, one on top of the other, to give it more space. The cage must be raised off the ground, or your guinea pig may get too cold, and the wood may start to rot. You will have to place the cage high up, for example, on a table.

An old cupboard or small cabinet can also be easily transformed into a guinea pig cage. This will save you on materials and avoid building the structure yourself.


2. Gather the Materials

The best outdoor cages are made of solid wood, which helps protect the guinea pig from the elements while providing good insulation. A well-designed cage also helps preserve your tiny pets from potential predators. So, in all cases, you should avoid buying cheap plywood. You will also need the following tools:

  • Wire mesh
  • Wood staples
  • Screws and/or nails
  • Galvanized hatches
  • Electric drill
  • Hammer
  • Screwdriver
  • Cutting pliers
  • Saw

Note: If you don’t feel comfortable building the cage yourself, you can find ready-made ones or easy-to-assemble enclosures at a pet store. In this case, the instructions will help you assemble the cage.


3. Build the Wooden Frame

Start by taking the measurements and cutting the wood. You will need at least four pieces of lumber at each of these lengths, more if you are building individual frames for each of the six sides of the cage and the door. Measure the wood, and double-check your measurements before you cut it. Using the drill, drill holes slightly smaller than the screws you have, then insert the screws between the different pieces of wood to assemble the frame.

Note: Building the frame can be quite tricky. If you do not have much experience with these tools, you can purchase ready-made frames at a pet store or on the Internet.


4. Install the Floor, Walls, and Roof

The outdoor cage should have a solid floor made of wood or plastic. Although some people recommend using wire mesh for the floor, it can be dangerous for your guinea pig, as he could easily break his leg. The roof should have a slight slope backward so that rainwater can flow into it, and you should cover it with two or three layers of bitumen felt to make it waterproof. The walls should be made of chicken wire that you cut to the correct size before securing it to the frame with wood staples.

Unfortunately, the wooden floor will absorb urine. You will therefore have to cover the bottom with a substrate and change it regularly. Timothy straw is excellent for this. In addition, some guinea pigs may gnaw on the floor, which will require you to change it more often.


5. Protect and Insulate the Cage

To protect the cage from cold, heat, mold, urine, and animal feces, you will need to cover it with wood varnish. You must choose it carefully so as not to make your pet get sick. Look for a polish that you can use specifically for guinea pigs’ cages. If you want to keep the cage in a semi-open place, applying varnish is not as important, but it can help extend the life of the cage.

Important Tips:

  • Do not put a guinea pig outside in the middle of winter or fall. Your small animal must be able to get used to the temperature before living outside. You can gradually get him used to the cold by taking him out in the spring when the temperature drops below 59 ° F.
  • Guinea pigs should live in groups of at least three to four animals so that they can cuddle up to each other on colder nights.
  • You should also place their cage in an area of ​​your yard that is sheltered from the wind.
  • Remember that a guinea pig that lives outside will need more calories to fight off the cold. Therefore, you will have to modify his diet during the winter: give him carrots, fennel, beets, and add a little vitamin C to the water to make your pet’s immune system more resistant.
  • Be careful that their water bowls do not freeze!
  • Clean the cage every two to three days.
  • Observe your animals regularly for any signs of distress or illness.

Final Thoughts

In short, you can take your guinea pig outside, as long as you follow basic precautions and don’t forget to visit him every day! But more seriously, think carefully if you want to invest the time and money in building or purchasing a suitable outdoor cage for your little rodent. And in any case, don’t leave him alone and consider adopting two or three other furballs to keep him company.
