Yea, racoons are bad but a fox will take one right from under your nose in broad daylight!
I recently lost three of my four girls while they were free ranging. I happend to be in and out of the house that afternoon and wasn't paying enough attention to where they were ranging. They went to the edge of the woods and were scratching around in the dead leaves finding all kinds of good stuff. When I saw them I should have tempted them away with a treat, but I got lazy and figured they would be okay. PROBLEM #1. Never think they will be okay alone while free ranging. "I'll just leave them for a minute." That's all it takes.
I have to agree that racoons are very smart creatures. They can easily open a latch with their little "hands." But, they can be caught rather easily in a havaheart trap. Foxes are pretty smart when it comes to the havaheart traps. Very hard to catch! We did get a shot off at one of them last year, then we didn't see them for a long time. I say THEM because we saw two, together on a knoll in our front yard.
Now they're back feeding their spring time babies, again!
