The last meal was the one I listed above. I have been thinking along the same lines as you, I did not take the skins off (honest mistake, I simply forgot) of the turkey legs before I ground them up, and the butcher only had pork organs. I’m betting that I just went a bit overboard with the fats and skins. Also, like an idiot I skipped the part on feeding one thing at a time to assess tolerance. We knew that he had no tolerance for high fat and he has an outright allergy to chicken and starches. He’s handled turkey neck, and the offal that I’ve given him the past during holiday just fine.
I’m leaning towards the pork organs and the turkey skins causing the upset.
Like I said, he’s got a full appetite and absolutely loves this food, in fact he saw me go over to the are where we used to keep his kibble around the same time he eats and I swear he was about to cry thinking I was gonna give him his old food. As soon as I got his new food out of the fridge he got super happy again.
