Zoey's All Nighter

I closed the pet door behind Zoey when she went out about 6 pm and kept Cinny indoors all night, so Zoey would go home. However she was back here when I returned to work next day looking kind of tired. I think she was out all night as I doubt her masters would have let her out again so soon if she had gone home. I wrote letter to her master but haven't sent it yet, may review for editing. I don't want to insult her but something has to be worked out. I said in letter I think she should try giving him some dinner meat every night so she has something to look forward to. I don't give him that kind of food here, so I think that might work. I didn't sleep as well as I've been sleeping when Cinny is out, so perhaps Cinny cried in basement wanting to get out. No way to know.
