He did it TWO. MORE. TIMES.
Our response time improved dramatically with each incident - second time (4:20 AM), Mr.Q chased him out before he let the mouse go; third time (5:30 AM), we cornered him in the kitchen before he got near the bedroom. I'm pretty sure they were different mice each time.
Then he had the cajones to try & cuddle with me when the alarm went off. As if.
He is not my favourite feline right now!
