A very quick word of wisdom

Should you ever wake up at 3 am in the morning to the sound of cats fighting in your room, DON'T ask yourself how they got there. And on no account should you start imagining what other creatures might be hiding in your room (i.e. snakes, rats, cockroaches). It is absolutely not conducive to a good night's sleep and is likely to leave you grumpy the next morning.
Just in case it happens to you sometime.
