Buyer's Manual

With so many cat food alternatives available, deciding where to begin can be difficult. However, there are a few variables you might examine to cut down your options.

Most importantly, you’ll need to determine whether your cat is simply too sensitive or whether they have an underlying health problem that needs to be addressed.

It’s always a good idea to consult your vet about stomach concerns to ensure your cat isn’t missing out on critical care. It’s also the greatest approach to find out what food to acquire them because your veterinarian can propose a suitable formula.

Some merchants demand veterinarian approval before selling you a specific cat food, such as a prescription diet, so be sure you have a documented approval or prescription from your vet to present.

You should also consider how much money you have to spend. As we’ve seen, some brands are more expensive than others, so choosing a budget will help you focus down products within a specific price range.

The tastes of your cat are also important; some cats are picky and will only eat particular foods or brands.

The best way to determine whether a product is suitable is to read user reviews on various websites. When you don’t know which brand to choose, you’re likely to read reviews from people who have been in a similar scenario.


It’s time to take a step back. The Purina One Sensitive Skin & Stomach Formula is our top overall recommendation.

Blue Buffalo’s Sensitive Stomach with LifeSource Bits formula is our best value pick, and Hill’s Science Diet’s Sensitive Stomach and Skin Formula is our premium pick.
