Where ya going????

I had to go out tn the afternoon, I was giving a neighbour a cutting of one of my plants, Luna decides to run upstairs and jump in the bed and look out the window. 

I don't think she can see out, she maybe be big but but not that big. She started doing this about 2 weeks ago. 
She obviously doesn't realise if she put her 2 front paws on window sill she might just see out more
