Thanks for using Petco Pet Education Center, formerly Petcoach! There is really no need to do that. If she is being fed a high quality diet, all these vitamins are part of it and do not need to be supplemented. You can consider a multivitamin which would never hurt though in most cases it is not necessary. Good luck and have a great day!
