How to Keep Possums Out of Your Cat’s House: A Comprehensive Guide
Wondering how to keep possums out of your cat’s house? Focus on securing entry points, removing attractants like food, and deterring possums with humane methods to create a safe and possum-free haven for your feline friend.
Possums, those nocturnal marsupials often seen scurrying about, can be a nuisance, particularly when they decide your cat’s outdoor house is their new vacation home. Not only can they create a mess and potentially consume your cat’s food, but they can also carry diseases and parasites that pose a risk to your pet. Understanding their behavior and employing effective deterrents is key to successfully reclaiming your cat’s house and ensuring your feline companion’s safety and comfort.
Understanding Possum Behavior and Attractants
Before diving into specific solutions, it’s crucial to understand why possums are drawn to your cat’s house in the first place. They are opportunistic creatures motivated by two primary needs: food and shelter.
- Food Sources: Possums are not picky eaters and will happily consume cat food left out overnight, spilled seed from bird feeders, fallen fruit, or even garbage.
- Shelter: Your cat’s house provides a readily available, sheltered space, especially during colder months or when they need protection from predators.
- Location: Properties near wooded areas or with dense vegetation are more likely to attract possums.
Prevention is Key: Securing the Cat House
The most effective way to prevent possums from entering your cat’s house is to deny them access in the first place.
- Inspect and Seal: Thoroughly examine the cat house for any openings, cracks, or gaps. Use durable materials like hardware cloth, wood, or caulk to seal these entry points. Pay close attention to the roof, floor, and any seams in the structure.
- Elevate the House: Raising the cat house off the ground can make it less accessible to possums. Use sturdy blocks or legs to elevate it by at least 18 inches.
- Consider a Cat Door Design: Install a cat door with a flap that only opens when pressure is applied from the inside. This can prevent possums from easily pushing their way in.
Removing Attractants: Eliminating the Possum Buffet
Starving them of a reason to visit is crucial.
- Bring Cat Food Indoors: Never leave cat food outside overnight. Feed your cat during the day and remove any leftovers immediately.
- Secure Garbage Cans: Ensure your garbage cans are tightly sealed and stored in a secure location. Consider using bungee cords or locking lids.
- Clean Up Fallen Fruit: Regularly pick up any fallen fruit from trees in your yard.
- Remove Bird Feeders (Temporarily): If you’re experiencing a possum problem, consider temporarily removing bird feeders to eliminate another food source.
Humane Deterrents: Encouraging Possums to Move On
Sometimes, securing the area and removing attractants is not enough. You may need to employ humane deterrents to discourage possums from returning.
- Motion-Activated Sprinklers: These can be effective at startling possums and discouraging them from entering your yard. Place them strategically near the cat house.
- Motion-Activated Lights: Similar to sprinklers, motion-activated lights can startle possums. Use bright, focused beams.
- Repellent Sprays: There are several commercially available possum repellent sprays that use natural ingredients like peppermint oil or garlic. Apply these sprays around the perimeter of the cat house, following the product instructions carefully.
- Noise Deterrents: Possums are sensitive to loud noises. Placing a radio near the cat house and tuning it to a talk radio station or white noise can be effective.
Comparing Deterrent Methods
Here’s a comparison of common possum deterrent methods:
| Deterrent Method | Effectiveness | Cost | Ease of Implementation | Potential Drawbacks |
|---|---|---|---|---|
| :————————- | :———–: | :———-: | :———————-: | :——————————————— |
| Securing Cat House | High | Low to Medium | Medium | Requires thorough inspection and repair |
| Removing Food Sources | High | Low | Easy | Requires consistent effort |

Common Mistakes to Avoid
- Ignoring Entry Points: Failing to properly seal all entry points is a common mistake that allows possums to continue accessing the cat house.
- Using Poison: Never use poison to control possums. It is inhumane and can pose a risk to your pets and other wildlife.
- Relocating Possums: Relocating possums is often illegal and can be detrimental to their survival. They are territorial animals and may not be able to find food and shelter in a new environment.
- Using Ineffective Deterrents: Some deterrents, such as mothballs, are not effective and can be harmful to the environment and your pets.

Frequently Asked Questions (FAQs)
How do I know if a possum is living in my cat’s house?
Common signs include droppings (resembling cat feces but often with undigested seeds or berries), disturbed bedding, unusual odors, and, of course, sightings of the possum itself entering or exiting the house, usually at night. Listen for scratching or rustling sounds within the house, particularly during the evening and early morning hours.
Are possums dangerous to cats?
While generally not aggressive, possums can carry diseases and parasites like fleas, ticks, and mites that can be transmitted to your cat. They may also scratch or bite if threatened. The biggest risk is the potential for disease transmission. Consult with your veterinarian about appropriate preventative measures.
What diseases can possums transmit to cats?
Possums are known to carry diseases like leptospirosis, coccidiosis, and toxoplasmosis, which can affect cats. They can also transmit parasites. Regular deworming and vaccination of your cat are crucial for protecting against these diseases.
Can I trap and relocate a possum?
Relocating possums is often illegal and generally not recommended. Possums are territorial, and moving them to a new area can disrupt the local ecosystem and reduce their chances of survival. Check your local laws regarding wildlife relocation before considering this option.
What are some natural ways to repel possums?
Natural repellents like peppermint oil, garlic, and citrus peels can be effective at deterring possums. Soak cotton balls in peppermint oil and place them around the cat house, or scatter citrus peels in the area.
Will a dog keep possums away?
A dog’s presence can sometimes deter possums, but it’s not a guaranteed solution. Possums are often bolder than you think. A dog’s barking might scare them, but a determined possum will not give up easily.
How often should I reapply possum repellent sprays?
The frequency of application depends on the specific product and the weather conditions. Most sprays need to be reapplied after rain or heavy dew, typically every few days to every week. Always follow the manufacturer’s instructions.
What is the best time of year to possum-proof my cat’s house?
The best time to possum-proof your cat’s house is before they start seeking shelter, which is typically in the late fall and winter months. Taking preventative measures in the early autumn can help prevent possums from establishing themselves in the area.
Are there any plants that deter possums?
While not a foolproof method, some plants, such as those with strong scents like marigolds, lavender, and rue, may help deter possums. Planting these around the perimeter of your yard may provide a slight deterrent effect.
Is it cruel to deter possums from my cat’s house?
It is not cruel to deter possums from your cat’s house, as long as you use humane methods that do not harm them. Possums are wild animals, and it is natural to encourage them to find alternative sources of food and shelter.
Can I use ammonia to repel possums?
Some people suggest using ammonia as a possum repellent, as they dislike the smell. Place a rag soaked in ammonia near the cat house, but be aware of ammonia’s pungent odor and ensure it does not harm your cat. Ammonia must be used with caution, as it can be irritating or harmful if ingested.
What if a possum is already trapped inside my cat’s house?
If a possum is already trapped inside, do not approach it directly. Open all doors and windows and allow it to leave on its own. You might also try gently encouraging it to leave by making some noise from a safe distance. Avoid cornering the possum, as it may become aggressive. If it refuses to leave, contact a wildlife control professional.
