i adopted my first cat last month. i was given a little kit that included a small bag of iams original. i figured i'd keep him on the same food, so i bought a large bag of it. i went to the petstore to get a hairball remedy and the woman said i should switch to a better dry food. is iams bad? she gave me a sample of innova dry food. she said a better food will help my cat's coat and slow down the shedding.
