Growl was the word I was looking for.
Thanks.
But I do have a 3 month old who screams.
Possums are not aggressive, it won’t hurt you unless you grab it. Put some food out, leave the room for a while, when it comes out charge in and put a laundry basket over it. Then, just scoot it out the door. You need to find out how it got in. If it’s a baby you could have a momma possum in the attic.
If all else fails, and it is not a rat, call the county wildlife rescue folks. What county do you live in? I may have a number to call.
