If the food you are feeding is complete and balanced (should indicate on the packaging), a multivitamin is not necessary. The additional vitamins would be excreted. There are instances where a human can get too much of a mineral (thyroid patients, for example). So I imagine the same would be true of animals. Unless you and your vet determines a specific need for a supplement, I wouldn't give any.
