I use a special smelly collar for Juni, she kind of like it even. I don't. At least, the first days when it smells strong. After that, she walks like she is princess with that collar. Also, I have a Russian cat shampoo for her, it smell of herbs. Anytime I notice she scratches herself more, I use it and it's ok.
Kirsten, I am sure, Luna will forget about it as soon as the smell will go away.
