This site give it 4 stars, I would give it more like 3. They use pea protein to raise the protein level and vegetable protein is harder to digest. Relying to too much plant protein can tax some organs, kidneys for example, over time. Not saying this food would do that, but I wouldn't feed it. Eggs are the main source of protein. Eggs sources are explained in the review.
There is a lot of ingredients before the fat which makes me question the actual egg protein percentage of the food. Since ingredients are listed by weight, same weight or decending order, and you have six ingredients before the fat, I think it is low on meat protein and heavy on other ingredients.
But that is just my novice opinion, the site should know more than I do...I still couldn't feed it unless I read other reviews that agreed with this one. Well I don't think I could feed it, the pea protein bothers me and chicken with water included listed first.
