I've used this picture of Snowbelle before: She's quite the character. When she and the other barn cats are out of food, she comes to the house and meows at the door until somebody feeds them. When we step outside, she heads for the barn, as if to show us the way.
I usually buy big bags of Walmart's house brand of cat food, and all the felines like it just fine. Recently, though, we were patronizing a local grocery store when we were out of kitty food, so we bought their cheap brand, I believe called Always Save.
Snowbelle hated it. In the couple weeks we used it, I never saw her take a single bite, although surely she did, or she'd be starved by now; somebody was eating it, because by morning the dish was empty.
She'd come to the house to get us during the day, we'd go check... and there was still food there.
Yesterday we finally got back to the Walmart brand. I'm surprised Snowbelle didn't make herself sick, the way she dived into that grub!
Silly picky cat.
