Pretty kitty

Our cat went a little crazy last night. She sat at the living room
window and hissed and slapped the window. She was not a happy girl.
When we got up to see what was going on, we found this cat. Callie
wanted to get at her, but she's an indoor cat, so she just sat at the
window protecting us. (Just got a text fom MK. She said that Callie's
friend is back.)
