Goats: occasionally too smart for my own good

Now I love my goats.  They make me laugh every day.  They do however tend to develop some behaviors that also make me want to scream.  The most frightening at this time revolves around these kinds of latches:

And the fact that goats can open them any time they wants to.  Let's just make this clear: any time she wants to, a goat can get into 2/4 of the kidding stalls, the coop, the stall off the milk room, and THE MILK ROOM.  Did you know I keep feed in the milk room?  Fortunately none of them have figured out how to get open the twist top bins I use, even by knocking them over and jumping on them.  I am also grateful that, generally speaking, they only want in when I'm in there (they know I can get the feed cans open).

So now all my doors and gates have hook and eye latches higher than the goats can easily reach, too.  Or close with a carabiner.  Heaven help me if they figure out how to operate a carabiner.  This is also conclusive proof that goats are smarter than sheep - the previous owner of our property ran Katahdins, and found all these latches to be perfectly adequate.  He also kept several of the tube gates shut by hanging the chain on a nail.  Yeah, goats figured that one out in about five minutes.
