Nutrience Natural Fish & Duck is a good formula that does not contain carbohydrates in the main 5 ingredients and it has low glycemic carbohydrates in the rest of the formula, which avoid sugar peaks in the blood (only Nutrience Natural Fish and Orijen cat formula accomplish these two criteria).

The average rate of the main 3 ingredients it is 3.3 stars which is good.

  • Important: In addition of feeding wet cat food  you have to make sure to give your cat lots of water, especially with male cats that tend to develop urinary crystals.
  • This particular recipe is made of quality North-American and french ingredients. Cats seems to adopt it very well too, including cats used to raw diets and cats that have never eaten dry foods before.

The formula contains taurine, methionine and lysine which are very important aminoacids, but the nutritional analysis does not mention the other 8 essential aminoacids that cats need.

Nutrience Fish & Duck is a very good cat food for a maintenance diet, but it informs 3 of 11 essential aminoacids that cats need in the food’s nutritional analysis.
