The Year of Rat Part 2

Next morning, I was late for work, didn't check on my fellow mates. Mum as if sensing my curiosity, emailed me from work. This is what she wrote:

Hi bab

Gosh! Your good friend had stolen the sausage and escape
from the sticky trap. Now Dad & I are in a dilema how to trap
your little friend. Pls help to trick your friend out , please....

Hey have u got your leave already?

Also pls bring back my favourite tupperware to me today!!!

Have change some Hongkong dollars for our trip. Ha..ha some only
not enough yet cos we gonna eat alot eh

Love from your long winded mom

I didn't reply her email because I didn't know what to say. I went home and dad told me that the rats took the cocktail sausage and had cunningly avoided the glue. I thought it was all over for good, that their rats mania has finally stopped.
Tragically, mum is still obsessed with it because she called me yesterday at work and left me a voice message for me to call back.

Bee: Ya you called?
Mum: I got something important to tell you (sounded worried)
Bee: Yes.....
Mum: I tell you ah, those rats! I tried to capture them again but tak jadi. They took the peanut cookies this time right after you left for work. They always seem to wait for you to go first.
Bee: Er, I am working now, do you think we can talk about this later?
Mum: I was so frustrated, I threw everything away - the food, the cardboard. Eh, you got ANY IDEA how to catch them ah?

Can anyone help me with this?
