I can't believe I'm asking for cat advice, this is my 9th one and people usually ask ME! 
Anyway, Luna is about 4 months old, we adopted her from our local rescue centre two weeks ago.
Our other cats eat dry food (Sanabelle for 7 of them, and one is prone to cystitis so we feed her Hills c/d separately).
Luna ate adult Royal Canin at the cat's home - they gave us some to take with us when we picked her up, but now she won't touch ANY dry food, she'd rather try to steal from our plates! She's been on Whiskas Kitten pouches since she moved in, and I got her some of the Whiskas Kitten dry food too, but she won't eat it even when I cunningly try to hide some in the wet food.
We'd ideally like to have them ALL on dry food, as it's easier - and we have to stand there whilst she eats her pouches to fend off the other cats, who all think that kitten food smells GREAT.
She won't eat Dreamies either - she's intrigued when the other cats do, but won't eat them herself.
She's drinking OK - and I checked her teeth and they look fine. She's a normal crazy kitten in every way.
Is she just being fussy? DP wants to stop the wet food to see if she'll eat the Sanabelle eventually - I'm soft and am worried about starving the poor kitten (and I think she knows it!)
I'm going to drop an email to the cats' home to see if she was fussy there - she was in with another kitten, but must have been eating SOMETHING!
Any advice gratefully received - thanks!
