Poor Luna! I hope she starts to feel better soon!

I know all about the jealousy issues... believe me. I swear mine all want to claim a territory as theirs and they pee on it. It's been ages since I've been able to have a cat bed sitting anywhere, because about 30mins. after putting one down, someone would pee on it just to be spiteful. My fosters upstairs are much better about things, and they get all the cat beds they want!
