Oh poor Luna UTI's are not fun, my Bobo jus got over one about a month or so ago and he was going nuts over it. I'm glad you were able to get the medicine she needs, that way she will be cured as soon as possible

As for jealousy, I've never had that in cats before, but then again I really only have one cat, Cc our other older cat doesn't care about attention, but now that I have two, Bobo and Kalypso who knows maybe when Kalypso is older. But I hope that you can get it all solved soon. And Nancy would definately help
