We save the container the oil came in for disposal.
We save bacon grease to use in cooking. I'll try the thing with the birdseed. We feed the birds all winter, and have all kinds of wonderful little visitors.
I have to be careful about putting food out though. I used to put all sorts of crumbs, grease and such out on the deck for the critters. HB kept telling me that if I kept it up, we'd have rats.
Then one winter morning, he called me to come look...On the deck just outside the patio door, sat a fat little brown wood rat, munching away on some old dried beans I'd tossed out.
He scurried away under the deck when I knocked on the glass, and HB immediately put a cake of D-Con under there for him. Of course, we wouldn't have to worry in the summer time...the rat snakes love it under my deck.
