How do you do it, and how do you get them back?
My 5 month old kitten has escaped out of the front door. She has been allowed out in the secure/enclosed back garden before, but we've kept her in recently after she was spayed so she was desperate to get out and darted out the front door.
I can't see her anywhere now and not sure how I will get her back in
. When they start going out is it OK just to let them roam?
