Well, if yours outgrows the cuddles mrdavE, I can assure you, they will more than make up for the cuddles with their antics and incredible sense of humor.
Just as our babies grow into teens and adults, so do Greys and you learn to appreciate their independence, personality, wit and humor. It's always great to watch a baby grow into who they are, with much of it being directly attributable to how you molded and trained them during their youthful years. :-)
