I wouldnt feed only dry, and especially not if you want your cat to loose weight. Dry is carb heavy, even the so called weight loss brands. I'd feed her a high meat content wet food with no grains, cereals or veggies, such as Hi Life, Bozita, Forthglade, Nature's Harvest. Applaws wet is also pretty good (although does contain some rice and is not complete). If you want to feed some dry, go for one that has no/low carbs such as Applaws dry or Orijen dry.
