Yes, definitely bad advice you've been given at PAH! Dry food isnt the best food for a cat as Spid mentioned. Have a look at this site to understand why
Feeding Your Cat** Know the Basi - but in a nutshell, its dehydrating, full of carbohydrates which cats dont need, and protein quality is not always good (often plant proteins are used). Agree with Spid's advice, high meat content, no carb wet foods, or raw, are better.
