How to dispose of bacon grease?

When we make bacon for breakfast, we are always conflicted about how to dispose of the bacon grease. 

Today... after all of these years... Dear Husband mentions that his grandmother used to make homemade bird cakes out of it.  She would add birdseed and then leave the cake out for the birds. Really?  And it only took you SEVEN years to mention this?  Really?

We quickly found a bird seed cake recipe online and started mixing.

I don't have a fancy mixer at home.

But I do have one of these little guys and he's all the help a mom could want.

He mixed until the birdseed looked like this.

Then the we threw the mixture into old containers that we dug out of the recycle bin.

Now, the birdseed cake is hardening in the refrigerator.  We are trying to figure out a way to leave it out for the birds while still keeping the squirrels away.  You know how I battle with those little squirrels.

Do you have a creative way to get rid of bacon grease?
