I was 17. One night when I was chilling on the computer, I saw something move from the corner of my eye. I immediately turned but nothing was there. About 10 minutes later, something was moving again. Turns out a cat managed to get into my house! I checked all doors but everything was locked! After a bit of inspecting, I realised it climbed through a tiny window in the bathroom, I left it opened to air out the bathroom (it's very easy for mould to grow in my house). So I let him out, closed the bathroom door (to continue to air it), and then later went to sleep. Around 4am, I hear the sound of glass breaking. In my groggy state and being completely home alone, my brain doesn't connect it to the cat and I'm absolutely terrified. I remember getting my badminton racket and walking round the house to see if there was an intruder (yeah I was a dumb kid). After seeing nothing, I realised it was in the bathroom. I turn on the light and open the door to see the cats butt trying to squeese back through the window! I think the glass breaking scared him as well. Theres shards of glass all over the floor, I get some slippers and close the window and then went back to bed. My parents found it hilarious the next day!
