Well, I can tell you that my Molly has horrendous poops on every food (the food that worked best was Timberwolf Organics, but the poops were still stinky). I recently put her on RAW and now you can't smell anything. Granted, I haven't been in the room yet when she's taken a poop, but usually when she DOES take a poop, it wafts into every room and you can smell it at the other end of the house within 10 minutes, and that hasn't happened yet since she's been put on a raw diet.
I wouldn't recommend going back to dry, though. I think it'll wreak havoc on her system (cats and dogs will go through a detox period for the first week on a RAW food, which is basically diarrhea, until all the evidence of dry food is eliminated from the animal's system), plus the digestive system changes when on a RAW food. If you put her back on a dry food, problems may come up, because she can't properly digest it, since her stomach will be digesting it as if it were RAW meat. Now, I can't tell you WHAT would happen, since at the moment I can't remember if the stomach digests raw meat fast or slowwwww, but I have heard several times that the digestive process is different with dry and raw food.
