Only the good stuff! Stella and Chewy's believes cats deserve to thrive on real minimally-processed food - the way nature intended. Because the closer foods stay to their natural state, the better they are. That's why they use raw, cage-free poultry, with no added hormones or antibiotics, and wholesome fruits & vegetables. All Stella and Chewy's products are made without grains, gluten, fillers, artificial preservatives or colorings.
