Are there foof dishes that will release measured amounts of food at specific times? Would something like that work?
If it isn't food it may be boredom. Have you tried playing with her rright before you go to sleep to wear her out? I only ask because that description of her meow sounds a lot like Misty's "i want to play" cry (without actually hearing it I can't be sure)
