I came home and my outside window to my cat room was broken. 
Cat room? I've never heard of such a thing.
A room for my cats! It makes me feel scared as I am in a bad neighborhood and would like to know what happened when I wasn't home?
Did any of the cats get out?
No. They had a screen in front of it- the window opens out- It's old- but I don't understand who broke it? And who was in my yard? 
Maybe you should get cameras
