One of my cats used to drool a lot (may be mistaken for sucking). Apparently that also is a sign of being taken away from their mother too soon. Drooling when being comforted or sleeping shows that they are preparing to suckle.
But I suppose all cats are still partially kittens. The kneeding they do is what kittens do to their mother's teets to stimulate milking.
