As long as she is gentle, Lee is allowed to play with Nin. At almost 18 years of age, he will tolerate her for a few minutes before taking off! Here are some pictures of them playing (taken from the stairs looking into the living room)
As you can see Nin doesn't love this!
PS: Thank you all for your comments on the bathroom. Most people like the green but I really only like blue, so anything that is not blue I don't love!
