Cats eat plants (mostly grass) if they want fiber to ease their bowel movements, or when they want to settle their stomach. Cats will also nibble on flowers for the same reasons.
Carnations, however, are a part of the compositae family of flowers, which have some toxic potential. It can cause drooling, vomiting, diarrhea, depression, anorexia and loss of coordination. I would recommend that you either remove them from your house, or garden, if your cat eats them regularly. If this is a once in a while thing, then keep an eye on the cat, and make sure it's alright.
