Well, it's been a couple of weeks since I started giving the rodents the hog feed. The food itself, the rats and mice seem to like. It's the size of the little pellet that makes it a pain in the butt to feed. It falls straight down to the tub with the 1/2 inch hardware cloth, so I still give the rats the rodent block & then couple times a day I give them a small handful of the hog feed.
Now for the 1/4 hardware cloth, the hog feed works great. A small portion of the pellets still fall through the mesh when pouring the feed but nothing too significant.
So I think for now, Im going to stick with the rodent block for the rats (even though it's $10 more per bag) and I'll just use the hog feed for the mice.
