Steve Versus ... the Flying Squirrels?

So after I found the cap I invested $2.33 in additional hardware to better secure the cap than with the bungie cord.

The clamps are rated at 50 lbs, surely more than enough to hold.

Loaded up with two more cakes. And now we wait for darkness.

D'oh! The cap is still attached, but it is flipped over and out! And the top cake is gone.

And as I watched I saw a Southern Flying Squirrel come down the tree and into the feeder, mulching away on the remaining suet cake. By morning both cakes were gone.

Mystery solved?

And more work to do.
