That these hulless pumpkin seeds are higher in phosphorus than Calcium is actually a plus, for they can be used as a substitute phosphorus source
in place of inorganic phosphorus (commonly added to block diet sources) that veterinarians note lends to the formation of bladder stones in rodents.
Another trade out would be English Walnuts for Pecans, as they are higher in protein content, and lower in cost than the Pecan, that should lower the cost overall.
I wouldn't forget our American Red squirrel buddies; amongst other sources more suitable for Pine squirrels include hazelnuts,
and Nevada Soft shelled Pinyon pine nuts that have a Ca:P ratio close to that of the Pecan.
