最后决定用Instinct Ultimate Protein, Made in USA, only real meat, gra

Made in USA, only real meat, grain free, no animal meal, no peas, which I found in Orijen, new formula Instinct raw coating, and many other grain free food, since pea is a low-cost thickener. 

I'm not 100% satisfied with GO's ingredients (b/c there are peas, potatoes), but I will probably use GO/NOW (same manufacturer) as alternative.

抱歉中英夹杂了，赶时间去机场。有时间再详细回复。
