<human>: ok, so heres the story. a few months ago i moved into a condo sublet with 3 other random people. they seemed ok at first, none of them were "cat people" per say but they were more than happy to have them it seemed. one night i got home from work around 8 and went right to bed. woke up to hear them chatting outside my room about how they have let the one cat out before and it came back so they didnt care. no more than 10 minutes later, i hear the one come back down and say hes just let it out again. i haven't seen it for a week (posted missing posters and such). and nothing. now i came home today only to find the other is now missing. they dont know i've overheard them saying they did it. now normally i would have already dealt hefty punishment for this. but seeing as i have to live with these people for another 5 months and cant afford to go to jail (or at least get caught for something) a frontal approach isn't feasable. what should i do?

Can you condense the text into three sentences or less?
<bot>: roommates let both my cats out within a weeks time. they don't know i know they've done so. i need to seek revenge.
