She had problems to digest the diet food so I got a paste from the vet (Uri-Pet) which is supposed to keep the pH-value of the bladder in balance (to prevent new crystals) but obviously it's not working...

Need to discuss this with my vet the next days...

Feeding an extra diet would also mean I would have to feed Luna and Lily seperated from each other forever. And this would be hardly possible because Lily never eats her food at once.
