Guinea pigs are adorable pets that bring joy to many families. However, they can also attract unwanted visitors, such as rats. This comprehensive guide will provide detailed information on how to keep rats away from guinea pigs, ensuring the safety and health of your furry friends.


To keep rats away from guinea pigs, maintain cleanliness in and around the cage, secure the enclosure with small bar spacing or solid walls, elevate the cage off the ground, and use rat repellents like peppermint oil and baking soda baits. If rat presence persists, consider involving a professional pest control service, ensuring they use pet-safe methods.

The Threat Rats Pose to Guinea Pigs

Rats pose a significant threat to guinea pigs due to their incompatible behaviors, aggressive nature, and potential for disease transmission. As omnivorous predators, rats may attack guinea pigs, causing severe injuries with their large, sharp teeth and claws. Additionally, rats can carry diseases like rat bite fever, which can be harmful to guinea pigs.

Signs of Rat Presence

Identifying rat presence early can help protect your guinea pigs. Common signs of rat activity include rat droppings, chew marks on the guinea pig’s enclosure, stolen food, and nesting spots within the cage. Regular inspection of the guinea pig’s living area and quick action upon noticing these signs can prevent harm to your pet.

Steps to Keep Rats Away

1. Maintain Cleanliness

Rats are attracted to food and waste. Regularly clean the guinea pig’s cage, remove uneaten food and waste to minimize the smell and reduce the chances of attracting rats.

2. Secure the Enclosure

Ensure that the guinea pig’s cage is secure and rat-proof. This may involve using cages with smaller bar spacing or solid walls to prevent rats from entering.

3. Elevate the Cage

Raising the cage off the ground can make it more challenging for rats to reach your guinea pigs.

4. Use Repellents

Consider using natural deterrents like peppermint oil, which rats find unpleasant. However, ensure your guinea pigs are not in the room when you spray the peppermint oil, as it can be harmful to them.

5. Set Traps

Rat traps can help catch any rats lurking around the guinea pig’s enclosure. Be sure to place the traps away from the guinea pigs to prevent accidental harm.

6. Keep the Area Clean

Ensure the area surrounding the guinea pig’s cage is clean and free from clutter, which rats can use as hiding spots.

Effective Rat Repellents Safe for Guinea Pigs

Peppermint oil, baking soda baits, and humane traps are some effective rat repellents that are safe for use around guinea pigs. However, avoid using ultrasonic pest repellers as they can cause distress to guinea pigs and other small pets.

Making Guinea Pig Housing Rat-Proof

To make a guinea pig housing rat-proof, use a cage with small bar spacing, reinforce the cage with hardware cloth, use fine-mesh fencing wire or chicken wire for outdoor enclosures, and secure the cage door.

Involving Professional Pest Control Service

If rat infestation persists, involving a professional pest control service may be necessary. Inform them about your guinea pigs, ask them to use pet-safe methods, and remove your guinea pigs and their belongings from the area being treated.

By following these steps, you can ensure a safe and healthy environment for your guinea pigs while keeping rats at bay. Remember, the key to successful rat prevention lies in cleanliness, vigilance, and appropriate preventive measures.
