Thanks for that.
Remember everyone that this is a very subjective topic.
Always look at what scientific backing diets have and by far the best thing to look for is a diet that has gone through AAFCO feeding trials.
A diet that is "formulated for" or to etc etc does not mean that it is a good diet. All it means is it has the basic ingredients. It does not mean the diet has been tested and made sure that it is acceptable.
Stick with AAFCO feeding trial diets and you won't go wrong
