This is wet food intended for the treatment of struvite. My cat prefers wet food from other manufacturers, so I have some of this left over. This therapeutic food has a minimum purchase quantity of 12-24 pouches from the manufacturer and Amazon. Since there are no samples of wet food, I have created a set of 2 pouches for owners who want to try 1-2 pouches first. Expiration date: 2027/1/26 After purchase, it was stored in my pantry at home. Shipping will be via Yu-Packet Post Mini.
