The best food for the cat is raw. It will be much easier to get kitty to lose weight on a raw diet. The next best option is some varieties of low calorie canned, but canned foods are usualy more expensive, particularly the low calorie ones.
I would not recommend feeding kibble for weight loss. All kibble is loaded with carbs, which makes the cat fat. Even the high protein, no grain varieties have a high carb content.
I am not sure if you are feeding your dogs commercial raw, which is also on the expensive side, but I feed my 4 cats franken prey and it's way cheaper for the 4 cats than what I spent on canned monthly in the past.
