My silly cat

My younger cat Nala did something pretty silly this afternoon. I have a loft in my apartment where I have my computer. I was up there today and my two cats normally follow me up there. There is a rail and a perch where my cats sometimes jump on. Well today, Nala decided to try her luck with the rail and lost her balance. I didn't witness the actual fall. All I know is that one minute I know she is upstairs with me, the next minute I hear a small cry from my cat and a thud. When I looked up she was gone and I saw her run into another room. She seems fine though after dropping about 15 feet or so. Hopefully she learned not to try walking on that rail again.
