same problem here !!! surely about wet food!!
Sydney gets dry food twice a day . I used to give him wet food at lunch , but he is sooooo difficult that sometimes he makes me nuts !!! Same as your kitty !!! One day he loves it --> makes me buy a supply of it --> next day he refuses it and lets it rotten !!!!
So now , I only give it to him when he "asks" !!! How does he do that ??? He goes and sits on top of the cabinet where all his wet food is , and looks at me with that "LOOK" ......... !
Well , up to now , we seem to "understand" each other !!! Great funny Sydney !!!!!!!
