If she is getting on the table to look out the sliding glass door then I'll give her another place to look out. I don't care if she is on the back of the couch or the window sill so I pulled up one of the heavy blinds on the windows behind the couch.
Yes, the table is the highest place in the kitchen/family room (cafe height table) other than the top of the folded up treadmill, which she also gets onto.
