Whelennut: In Montana they are classified as "Varmints" no license needed, no limit, no closed season!
I have shot quite a few of them.
Here's a quick story about Raccoons and their nest robbing.
This past spring I was asleep and I hear this great big thump/thud noise outside my bedroom window.
I get my light and gun and go to see what was going on.
I had a "Bluebird" style bird house attached to a tree with heavy plastic slip-ties!
A family of Raccoons had climbed up the tree 6 feet and gnawed through (or they might have used a switchblade knife?) the plastic slip ties and the bird house crashed to the ground.
The largest Raccoon had his arm inside the bird house and was "fishing" for eggs/birds!
I put an end to that in short order.
Indeed Raccoons are nest robbing experts and as such have earned Varmint status with me (and the state!).
