How about just mixing 1/4th to 1/3rd cup raw ground beef, ground turkey, or ground chicken with about 1 cup of warm water, then add your Fromm's and let soak for about 30 minutes to re-hydrate the kibble a bit. The meat from the grocery store might be cheaper to use! 2 cups = 1 pound so if you feed 1/4th cup 2 times per day it should last about 8 days!
You can also try a couple of tablespoons of canned Mackerel or canned Sardines in water.
These things seem to work EVERY time!
