I switched Gizmo to this food about 2 months ago in my search for a non-poultry food without Rosemary extract. In the past 3-4 weeks he's been vomiting approximately every other day. The vet put him on Pepcid & a bland diet for a week. The day I took him off the bland diet & pepcid, he vomited again. I'm going back to the pepcid & mixing the bland diet with this food again to see what happens. I'm wondering if it's the food and if there's maybe an ingredient that doesn't agree with Gizmo. Or maybe it's just too rich for him? Poor thing...he loves it far more than he did the Natural Balance (which he just stopped eating one day). Wanted to see if anyone else had any experience with this food. Thanks!
