Thanks for the info(: I'm not really sure what to do. I did put the cranberry juice back into the water and I felt around the cage for wet spots. There are a few, but I assume they dry within half an hour or so. I also wash the fleece weekly. I checked the yellowing again, and it's barely wet, it just looked wet. I wiped it with the baby wipes and a little did come off. With UTIs is there usually vulva swelling? Because if so, I remember the vet saying she didn't have any.
