Thanks for your kind words everyone! I'm sure Luna appreciates it, too, even though she's still a bit confused.
But she's doing better meanwhile, she's not so dizzy anymore and a few minutes ago, she jumped onto the kitchen counter. And she starts grooming and is more active now.

Edwina's Secretary, she has cat grass and she even eats it, but never vomits hairballs. I'm also feeding her Hill's Hairball Control which contains a lot of fiber, but we've been running out of it during the last weekend, that was when the problem occured.

Spencer, the vet thinks that her colon is working slowly because Luna has become so lazy. I hope I'll be able to move into a bigger appartment next year so I could get Luna a little kitty friend to play with. That way she will be more active.

However, thanks for your replies, I hope Luna will be alright soon! What an awful day for her today!
