            Vitamin A



              Vitamin A (Adult cats) The FEDIAF maximum is based   a  Seawright  AA,  English  PB,  Gartner  RJW.  Hypervitaminosis  A  and
            on the study reported by Seawright et al. in kittens. a  deforming cervical spondylosis of the cat. J. Comp. Path.1967; 77: 29-39.

              The FEDIAF maximum of 40 000 IU/100g DM is about
            50% of the maximum NOAEL reported by Seawright et
            al.   in kittens from 6 to 8 weeks of age fed for 41 weeks.
               a
            Since kittens are at least equally vulnerable as adults
            to hypervitaminosis A, this level should also be safe for
            adult cats.

              Vitamin A (Growth and reproduction) Seawright   a  Seawright AA, English PB, Gartner RJW. Hypervitaminosis A and

              In view of these data, FEDIAF recommends a
            maximum vitamin A level of 33,330 IU/100g DM for
            products designed for reproducing queens.
