Jazzcat, that Nature's Miracle sounds good, but I never heard about it here before! Will try to order something like that online because I'm sure this isn't the last accident!

Jen, I also think it's medical again, even though she's still on a prescription diet... But she's also eating from Lily's bowls now, + the stress after Lily's arrival...

I hope I don't have to keep her seperated to retrain her, that would break her heart - and also mine.

I didn't add another box after Lily's arrival because she had three already! They were all in the cat room and when Lily first slept in the cat room during her first days here, Luna peed into the hall. After that incident, I placed one of the boxes in the hall which she is mostly using now. Even though I'm cleaning the boxes at least twice a day, it may not have matched her hygienic standards because later today, she pooped onto the floor in the hall. After that, I gave her box a very intense cleaning. But I wouldn't be surprised if there are struvite crystals again.

BTW, did you make any progress with your peeing problem?
