Celia would only eat pates as well, and while there wasn't any food that she really seemed to love, the foods that she ate for the longest (other than Fancy Feast) were Dave's and Holistic Select. She wasn't a fan of chicken, but both brands do have a chicken pate.
I also ran out of pate options at a certain point, so I started getting other textures and pureeing them in a mini processor. That worked for some foods, but it doesn't work with anything that comes in shreds. Shreds are puree-resistant. I did have some success taking a pair of kitchen shears to a can and snipping away, but it still wasn't smooth, so she still wasn't a fan.
