Science Diet is supposedly a premium food, but I don't like the fact that corn is the #1 ingredient. Try Nutro Max instead.... a few dollars cheaper and no corn.

Are you feeding them dry or wet food? Stop the wet if you are, since that can contribute to runny poo in some cats too.

PS: despite it being more expensive per bag of food, it actually is somewhat even in the end because cats eat less at a time (less fillers, more proper nutrition) and they poop less, which means less litter to scoop and less litter to replace at the end of the week.
Ah, took the words right out of my mouth I couldn't agree more.

Science Diet is OK.. but for the quality its a bit overpriced for what you're paying for... which is mostly corn.
