I am convinced our cat Yağmur goes night clubbing every evening. Now the nights are warmer both cats disappear during the evening. Kar stays out all night returning about 5am but Yağmur returns in the very early hours.
Every morning at about 1.30am he is at the bedroom window meowing to come in. My guess is the night club closes at 1am and then he comes home.

After breakfast he goes out and settles down on the bike to sleep.
