Cats must be given the correct amount of nutrients and vitamins to keep them in good pet health as they age. Owners who feed their cats large amounts of liver or other supplements may be putting their felines in danger.
According to VCA Animal Hospitals, human food tends to be higher in vitamin A, which could lead to hypervitaminosis A, or vitamin A toxicosis in cats. This condition can lead to serious problems in cats. VCA reports that a form of arthritis in which new bone develops around the joints is the most common sign of excess vitamin A. An affected cat may become immobile or slower, at which time it should be brought into the veterinarian health clinic for a complete physical and potential treatments. Signs of vitamin A toxicosis usually take a long time to show up.
VCA reports that feeding a cat too much organ meat, like liver, or over-supplementing it with cod liver oil pills or liquids are often reported as a cause of vitamin A toxicosis. Although not all cats fed high amounts of vitamin A will develop a problem, it is difficult to predict which cats will be susceptible to and develop the disorder. VCA suggests that owners feed their cats high-quality food that is complete and balanced for the needs of cats and give supplementation of oils, vitamins or other foods only with the knowledge of their veterinarian to avoid problems with vitamin toxicity.
