If you watch a woodpecker feeding, they're always clinging to a tree with their tail braced against the trunk. A suet feeder with an extension below the food, "tail board", allows them to feed in their normal upright position:

The dividers on my mold are finger-jointed. The lower set is screwed to the base and the upper ones just interlock to them for easy removal. That makes it real easy to remove the cakes after they harden. You can make the overall size whatever you want, depending on how many cakes you want to make. If your SIL needs any information just let me know and I'll furnish more detail.
