My cat was taken from her mother too early. What can I do?

I have deduced from two other problematic cat behaviors that my cat was most likely taken from her mother too soon, resulting in improper suckling and other activities.

Is there any way to effectively “rehabilitate” a cat? And this isn’t just a minor issue: my cat wakes me up every night, wailing and suckling on anything white and fuzzy that I forget to put away.

I need to sleep again!
