Alright food

I've been trying to find a low phosphorous food for my cat for a while. While this does have low phos I think it is very high carb and gave my cat gas. While it is a great price and the ingredients are alright. What I really don't like is they don't list where the ingredients come from stating that it changes due to the market. So, I'm assuming, basically you're getting the cheapest quality from asian countries. If it came down to this versus something like Purina Cat Chow etc., this is better. I think I'm going to try Now Senior instead though so I don't have to worry about ingredients as much.
