Aromatic attraction has come to the rescue.
I have two one year old cats, one of which is an extremely fussy eater and shows her displeasure of most cat foods by acting as if she was in her litter tray. I had tried Royal Canin before, but the Aromatic attraction has come to the rescue. She was suspicious at first, but was eating happily within the hour, along with my other cat who has 'gone off' the other brand my vet recommended. Very successful, thanks Royal Canin.
