I don't... understand everything you mean. I agree that a homecooked diet doesn't sound like the best option for you: 1/you might not find everything you need to supplement the cat appropriately, 2/it would require a lot of research on your part, and it kinda looks like you're a little overwhelmed right now. You can get dry food for your cat, and supplement her with Sheba wet food once a day. Just control how much she eats so she doesn't become obese, but the wet food will help keep her hydrated
