Ever spotted an opossum hanging around your yard? You might start to worry about your pets. Honestly, opossums almost never eat pets like cats or dogs. They’re scavengers by nature and usually steer clear of any kind of fight with bigger animals—including your furry pals.

Most of the time, opossums ignore cats and dogs. They’re more interested in easy snacks, like pet food left outside. If your pet gets a little too close or tries to mess with them, an opossum might defend itself by biting. Still, actual attacks hardly ever happen and usually only if the opossum feels trapped.
That’s good to know, right? You can feel a bit more at ease when you spot one of these odd-looking creatures nearby.

Do Opossums Eat or Attack Pets?

Opossums don’t like to fight, but they’ll stand their ground if threatened. They don’t hunt pets for food, but things can get tense when pets and opossums cross paths.
Risks to Cats
Opossums barely ever attack cats. Most of the time, they just want to avoid trouble and might even “play dead” if things get scary. If a cat chases or corners an opossum, though, a scuffle can break out. Both animals have sharp claws and teeth, so injuries can happen.
Sometimes, opossums steal cat food or chow down on leftovers outside. That can spark some drama. If your cat spends time outdoors, keep an eye out—especially after dark when opossums come out. If your cat gets hurt, don’t wait—take it to the vet.
Risks to Dogs
Dogs are bigger and usually bark at opossums to scare them off. If a dog corners one, the opossum might bite. Their teeth can leave cuts or wounds on your dog’s skin.
Opossums don’t chase dogs—they just want to get away. But if your dog pokes at an opossum that’s playing dead, it could get bitten. To keep your dog safe, watch for opossum activity around your yard. If your dog gets bitten, clean the wound and talk to your vet to avoid infection.
Risks to Birds, Fish, and Reptiles
Opossums sometimes go after small pets like birds, fish, or reptiles if they get the chance. They’ll eat bird eggs or small animals left outside if nobody’s watching.
Fish in ponds without covers or reptiles in outdoor cages are at risk. Cover cages and tanks tightly. That way, you’ll keep opossums out and your little pets safe.

Understanding Opossum Behavior and How to Protect Your Pets

Opossums are mostly harmless and don’t usually cause problems for pets. If you know what they eat and how they act, you’ll spot issues early and keep your pets safe.
Opossum Diet and Biology
Opossums eat insects, small rodents, fruit, and even garbage. They help control bugs and snakes, which is actually kind of handy. They’re nocturnal, so you’ll see them at night.
They don’t hunt big animals or pets. Opossums just eat whatever’s easy to find. Their defense moves are pretty simple—hissing, showing their teeth, or playing dead. Fighting isn’t their thing.
If you keep food out of your yard, you’ll make your place less attractive to opossums.
Typical Interactions with Household Pets
Opossums mostly avoid pets and don’t act aggressive. If you spot one in your yard, your dog or cat might bark or chase after it. The opossum will hiss or bare its teeth, but it won’t go on the attack.
Usually, pets and opossums leave each other alone. If your pet stays calm, the opossum will head off pretty quickly. Bring your dog inside during opossum visits to avoid stress or injuries.
If your pet does get bitten or scratched, get to the vet right away. Fights with opossums don’t happen often, though.
Signs of a Nuisance Opossum
Opossums become a problem when they keep digging through your trash or hide out under your deck. You might notice:
- Torn up garbage bags or food scattered around
- Tracks near sheds or under porches
- Weird noises at night outside your house
If you find baby opossums, don’t block their exits. Young ones under 7 inches long can’t survive alone and might need animal control.
If opossums keep coming back, it usually means they’ve found food or shelter too easily on your property.
Steps for Opossum Removal and Wildlife Control
Start by getting rid of food sources. Lock down your trash cans with lids or bungee cords. Pick up any fallen fruit from your yard—opossums love that stuff.
Try not to trap them on your own. Trapping can really stress these animals out, and honestly, it might even be illegal where you live. Instead, block off entry points under decks or sheds using mesh. Leave just one exit open, and set up a one-way door so opossums can leave but not get back in.
If you spot an opossum that’s stuck or hurt, reach out to your local wildlife control folks. Removal costs can vary quite a bit, but choosing humane, safe methods keeps both your pets and the opossums out of trouble.
