A topical subject in human nutrition is the steadily growing number of people choosing to limit or completely avoid all animal‐derived food products either for moral dilemma, health concerns or both. To meet people's will of applying their dietary choices to their domestic animals, the pet food industry answered by launching on the market some plant‐based diets. This leads to concerns about whether these diets are adequately formulated to satisfy the target species nutritional requirements, especially for cats which are still considered strict carnivores. This case report follows a 2‐year‐old male neutered Main Coon and a 1‐year‐old female spayed Domestic Shorthair cat, presented to the nutrition service of the University of Toulouse, France. Reason for consultation was lethargy with in anamnesis a recent dietary transition to a plant‐based pet food. Dysorexia, lethargy and muscle waste were present at first consultation. Progressive weight loss developed during follow‐ups. A macrocytic, non‐regenerative anaemia with serum folates below reference were the main clinical features. Analysis of pet food showed multiple nutrients below minimum recommendation at the average daily intake of both cats. Folic acid supplementation improved dysorexia, and subsequent reintroduction of animal‐derived ingredients in the diet restored appetite, weight and a normal mentation in both cases.
