<human>: Could you distill the essence of the text into 1-3 sentences?

I've had Luna for about a month. She's 5 months old now, and the past few nights she has been freaking out. We bring her to bed with us like normal, she use to sleep on my pillow above my head. But now she just runs off and starts scratching our mattress (which is another new habit). She'll jump on my boyfriend and I in bed. She messes with cords and even chews on my hair. She runs up and down the hallway meowing for no reason. She use to be super cuddly and let us hold her all the time. Now she just squirms away. She brings her toys into our bedroom to play with them. And we can't shut her out because we're pretty sure she has separation anxiety. We can't do anything without her meowing at us. If we leave the room without her noticing she'll meow til she finds us, and will continue til we pick her up. She sits in front of the door when she knows we're leaving. 

She has a scratch post and more toys than I'd like to admit. She's super spoiled, and I honestly can't stay mad at her and she knows it. As punishment for keeping us awake I'm not letting her nap today. Because of Daylight Savings I got 3 hours of sleep Saturday night. I was not pleasant at work the next day. I had to preoccupy her last night so my boyfriend could get some sleep for work today.

Is it just a faze some kittens go through? Or should we be worried?
<bot>: Cat either keeps us up playing with toys in our bedroom, or by meowing at the door because we shut her out.
