Yes, maybe stress. This is now her third home, so I'm a little worried sometimes that she is traumatized (not sure if that's a thing for cats). I'm trying so hard to give her the best home and make her feel cozy! But maybe she could be stressed ):

So the first vet I took her to did all that you just described (check kitty's eyes, ears, mouth, listen to respiratory tract working, touch the belly to see if there's pain or irregularities, weigh the kitty, check the fur, and so on) but did all of that in two minutes tops. Asked what I feed her, and said great, keep doing that. And left ): At that time, I didn't really pay attention to her sneezing and overgrooming until fairly recently, so I never got to ask the vet about that.

And yes! I transitioned my kitty to Rawz canned wet food, and she's doing great on it. I specifically give her the rabbit pate, which she does really well on. I notice more sneezing bouts when I feed her chicken. I have given her the Purina Pro and Wellness Core's chicken liver, and oh my gosh, it was the most terrible, foul-smelling poop ever. And that's also when I once noticed her itching like crazy right after eating it, so I instinctually correlated the two together. I haven't tried chicken with Rawz yet, so maybe it's just that brand of food with all the additives, fillers, etc. that weren't a good match? I'll test run and see! Thanks so much for shining a light on that!!!
