A grain free, fresh meat formula; it contains added prebiotics and natural antioxidants from turmeric, blueberry, and cranberries. Feline Sustain No. 29 is also MSC certified, ensuring that this sustainably sourced fish is traceable from boat right to the bag! A portion of the profit for each MSC-certified bag sold goes to helping protect the productivity and health of our oceans.
