I usually leave 2 bowls of 2 different brands out so my cat can have a choice. If she's not eating one particular brand, I discontinue that one and try another. So far, since I've introduced the Wellness brand, she's ignored it, but not much time has elapsed. Wed's and Sat's she gets a small can of Fancy Feast in a saucer. She's more of a licker than an eater. she'll lick up all the juice first, then lick on the fancy feast blob. Doesn't eat much, most of it is left behind, but it's her treat food that she really likes.
