A Rat In My room.

I am so exhausted from today's activities and I retired to bed by 8:20.

A sound woke me up and it's a Rat in my room, it's 12:30pm hear and I am up looking for the rat in the dark.

I used my phone touch to look around, I finally found it but it's had ran into my wardrobe.

Who did I offend?

Because I am feeling restless and I can't sleep because I feel the rat will climb the bed.....and I still can't kill it because I am scared.

I wish it can listen to me.

I would literally beg it to please leave my room and go to the sitting room or even out of my house.

Any suggestion on how I can get the rat out of my room?
