I've actually read a lot of bad stuff about Science Diet.. Cause of all the corn/grain and by-products in it. So if I were you, I'd take her off that asap. ..Make sure you go to those links I gave, they have really good info. ..Also, here's a site about what's really in pet foods http://www.shirleys-wellness-cafe.com/jesse.htm
...There's actually euthanized pets & road kill in a lot of pet foods (even the more expensive high quality ones)... So check that site out, really interesting stuff.
