Cat outside the window

He is trying to open the window? Nobody  knows :o)

This picture is taken at about 10 pm at Tuan Anh's room. When he first saw the cat outside the window (he was on the 1st floor!), he called me to come. 5 minutes later, I came and took these pictures.

The cat was so funny!
