An opossum flat on its side in your yard, mouth open, looking stiff and gone, is probably not dead. It’s “playing possum,” which sounds cute but is actually an involuntary reaction to being scared. The animal isn’t acting. It literally can’t help it.
What’s happening
When an opossum is cornered and terrified, its body shuts down. It goes limp, its eyes glaze over, and it may drool or release a foul smell from its glands. That smell and the dead look are the whole point, they make a predator lose interest. The opossum stays aware the whole time, it just can’t move until the threat passes. Scientists call it thanatosis.
It’s not a sign of rabies, by the way. Opossums run cooler than most mammals and rarely carry the disease.
Signs it’s faking, not dead
- The body is limp and moves without resistance.
- The eyes are open but glazed and unresponsive.
- The mouth may hang open with the tongue out.
- Breathing is very shallow and hard to see.
- There’s a musky smell from the anal glands.
What to do
- Leave it alone. It doesn’t need your help and it isn’t hurt. Stay back.
- Keep pets and kids away. A dog will “investigate” a limp opossum, and the opossum may snap if the trance breaks.
- Wait. Most snap out of it in under an hour, though it can last a few hours.
- Don’t touch or move it. That can make the episode last longer.
- Call someone only if it’s still limp after several hours or clearly injured.
Frequently Asked Questions
Usually a few minutes to a couple of hours. In rare cases it drags on longer. The animal recovers when it stops feeling threatened.
Not while it’s in the trance, but if you poke at it and it snaps out, it may bite in a panic. Leave it alone and it’ll recover on its own.
No. If it’s playing dead, burying it would be cruel and illegal. Give it several hours before you conclude anything.
A truly dead animal stiffens up and won’t respond to anything after several hours. A playing-dead opossum stays limp and may have faint breathing. Wait it out before deciding.
