She's beautiful and I'm glad she is doing well.
I know you are worried about her having an RI but I wouldn't worry too much just yet. My baby girl started showing signs of an RI, I swear I even heard her cough or something similar at one point. I immediately made an appointment with my vet. It was only a day or so after I heard the weird cough noise that I got her in and by then most of what I saw had disappeared seemingly overnight. My vet didn't do a culture but he did swab the back of her throat because it looked like she had some mucus back there but there weren't any alarming levels of bacteria, they weren't above what would be normal levels. He said she might have a very mild RI that would have most likely gone away on its own and most owners wouldn't have noticed the minor signs I picked up on. So long story short, you might just be hyper aware of her right now and she may have had a minor RI that went away on its own.
