VET DIET.. URINARY Wet food for cats with bladder/ struvite (Hall Green B28)

Hi, my cat Farah, can ONLY eat a prescription diet of URINARY..REDUCTION OF STRUVITE STONE WET CAT FOOD.
Last month Zooplus, where I buy her food from On line had run out of her usual, so I got her another brand. ..SMILLA. Its actually a German brand ,with EXACTLY the same ingredients and purpose as the Purina and Hills one .
I ALWAYS buy her the SMILLA dry food as again , after researching ..same ingredients ,abt 1/3rd price and she loves it. . Soo, anyway thought wud have no problem with the Smilla wet. I was wrong! Fazza loves gravy..as u can see this is more of a solid paté, its also TURKEY flavoured, not chicken as I thought . She doesn't like it .
For ant cat lover/guardian that has to buy this Urinary prescription food, u will know its NOT CHEAP! I certainly don't want it to go to waste.. I have an opened box with 4 'tub' things left unopened in it, plus two more full boxes of 8 x 100g... FREE to any Cat that is ON THIS PRESCRIPTION URINARY WET FOOD !! PLEASE, PLEASE, UNDERSTAND !!!!!..CANNOT BE GIVEN TO CATS WHO ARE NOT ON THIS PRESCRIPTION DIET !!!! I CANNOT STRESS THAT POINT ENOUGH.
Blessings and thanks
