Here are a couple of thoughts...
Depending on how much time there is between when you get up and Jake's AMPS, if you can get a +11, along with an AMPS, that is another piece of information that can be very important especially since you are gone for a long period of time. It sounds like you get home right before shot time. If you're home earlier, get an "in the door" test. Otherwise, I would get in as many PM checks as you can.
Is there a reason you don't want Jake to have the Friskies? Those 2 varieties are 7 and 8% carb, respectively. The Newman's Own may be lower in carbs, but the Friskies is by no means bad. Since you've said you want to get Jake to eat, the Friskies is fine unless he's highly carb sensitive.
