Yes, it is definitely possible that you could see improvement so quickly! Some cats do take a bit longer, which is why it's recommended to keep at it for 8 to 12 weeks. I am so excited for you, and I hope that the food change solves the issue entirely!!
Once your cat's skin has completely calmed down and has healed, please DO try adding wet food back into her diet (give her a couple weeks or so). Pick one flavor, of one brand at a time. That way if her skin reacts, you'll know *exactly* what it was and can remove it immediately.
There are other brands of wet food you can try. What were her favorites? Does she prefer pate or shredded type canned foods? We can help you determine a few that might be the safest ones to try first.
