Cat flap

I started installing a cat flap in the door to my quarters, so Mittens can move from the library to my cell freely. 

Drama ensued. 

The station's quarters have a type of sliding doors full of electronics for proximity activation and breach detection. Little did I know I wasn't supposed to use a diamond blade jigsaw on that to make a hole for the cat flap. The breach had been detected, alarms were blaring in some control room, and half a brigade of armed security were moving in, stormtrooper formation.

Apparently there have been some security issues and attacks and such in the past at the Lamp and they're very very jittery. So when the alarms went off of someone sawing through a door they took no risks. But really, a stun grenade? Was that necessary?

And then you would think that they would be happy there was no real emergency this time (except for my eardrums), but no. I was told in a very impolite way to have the door replaced immediately and not to drill through it again.

To be honest, I was going to replace the door anyway. Turns out I hadn't thought it through very well: with the cat flap thing attached to it, the sliding door didn't manage to slide all the way any more, thunking the protruding cat flap against the side and going back and forth. 

Maybe I should make a hole in the wall next too the door?
