Ditto Maxyboo I'd starve the little thing for 12hrs - if it was an adult I'd do it for 24hrs, but babies I'd halve the time! Then I'd feed the kitten boiled chicken/fish with a bit of rice covered in the juice and a teaspoon of live youghurt. Keep the little sprog on this for a couple of days and then gradually start adding her food back in.
Has the kitten been wormed yet?
