Thanks everyone! Luna is doing very well with the antibiotics. Of course she hates to take her meds, I more or less have to force her to eat them, but so far it worked. And no diarrhea since!

stacwase, that's a good advice, thanks a lot! I didn't know about the joghurt, but it makes some sense - even though I think that in the end, Lily will eat it, not Luna! LOL But it's worth a try!
