He keeps letting our young cats out in the evening, though I have asked him not to as we don't have a cat flap and I don't like them being out all night. Last night he let them out at 9pm, one came back at 3am (DP got up to let him in) but the other still hasn't come home. It's the longest she's ever been out and I'm really worried something bad has happened to her. I'm pregnant so I could be over reacting as I'm very anxious about everything.
