My fucking "indoor cats" have found a way out. I have checked the windows. I close doors.
They both know how to get in.... when I hear the more dominant male asking to be let in, he will come inside. He's chilling on my bed right now. The female is still very skittish and hides away, so I am never sure if she is inside or outside... meaning I need to leave a way back inside open if there is any chance she is out.
Which gives the male a way to get outside. Catch 22.
At least she knows where her food is.
