New to site. Want to know if Smoky (10 week old female) is having trouble. Eats good (loves canned food). Doesn't need toys (plays with tail, large paper wads, large thick rubber bands, etc). Sleeps on pillow next to me at night, back of couch or me when watching tv. Her problem? At night she acts like shes nursing the blanket on the bed, she makes the sucking noise and leaves a little wet spot from flicking her tongue. She only does this at night and it doesn't last long. Should I discourage her? Sometimes I do but not all the time.
