One bag of brand new sealed Hill's Prescription Dirt y/d Thyroid Care Dry Cat Food. 8.5 lb. I have 2 bags. One bag expires in Jul 2024. The other one expires in Sep 2024. The listing only contains 1 bag as the Poshmark package is limited to up to 10 lbs. My cat eventually received I-131 treatment and no longer needs the special diet.
