Ladies,
HELP ME! My fiance and I are living apart for a few more weeks while he ties up loose ends in our old town, and I get us settled in the new. Consequently, our (originally his, I am marrying into their family

) cat, Cage, is here with me in the new place. During the day he is find, lazing about and doing his kitty thing. At night, he pulls a Jekyll and Hyde and goes completely bananas, yowling and whining to no end. It usually starts in the middle of the night while I am sleeping, but tonight it started as soon as I got home. It isn't a medical issue, as he was at the vet just weekend before last and is totally healthy. I actually think it is separation anxiety from my fiance not being here, and I don't know what to do. I have tried locking him in the bathroom in the dark to chill him out for a few minutes, those natural drops that are supposed to mellow them out, playing with him until he is tired, everything so it feels.
Is there anything you girls can recommend that might help him chill out, and in turn, let me chill out? I can not take one more night of no sleep, and I hate that he is so wound up!
