I have a ferret and they are carnivore... but she eats vegan/vegetarian and is healthier than when I first saved her...she was extremly skinny and sick and it isn't wrong as long as they want to eat the vegan food you give them and that you supplement their diet with protein and know what they can't eat ......
Ferrets are predators and strict carnivores and therefore require highly digestible, meat-based proteins. They cannot survive on vegetarian diets or most dog foods, as there is too much vegetable matter in those products, and too much carbohydrate in the diet can create health problems in ferrets.
If feeding dry kibble, be sure that the food contains at least 30 to 40 percent crude protein (of animal origin) and 15 to 20 percent fat. A thorough reading of the label is crucial—the first three ingredients should be meat-based. Avoid processed treats marketed for ferrets, as they tend to be carbohydrate- or grain-based. Supplements should not be necessary if the optimal diet is being fed. For more details, please read “Rethinking the Ferret Diet” by Dr. Susan Brown.
