An analytical paper looking at the cause, signs and treatment of improper nutrition in animals
If vitamin A is not fed correctly within the diet then cats can suffer from a vitamin A deficiency. In many animals, the yellow pigment within plants called carotene is consumed and the carotene is converted into usable vitamin A. Cats do not have the ability to change this carotene into usable vitamin A and need to get their usable vitamin A from sources such as fish and liver. A lack of this vitamin can make an animal more susceptible to infections and stress.
