Now I've brought her to several vets and they all say she is perfectly healthy. I just fear my Luna is starved for attention and there isn't much I can do...is there any way I can calm her down? Maybe get her to stop meowing so much? It's been 2 months and we haven't slept properly since we got her. And no I will not give her up. She is part of our family.
Look up "How to Properly Play with your Cat" by Jackson Galaxy. He did an episode like this on his show "My Cat from Hell", but I can't find the episode, and I'm not quite sure I remember how he solved it... I'm sure the majority of it was to play properly. And maybe for the kitty to have their own little place where you spend the majority of your time?
Also, some cats are just a lot more vocal. One of my cats, named Baby for his constant crying is the happiest, most spoiled cat ever and he's still a meowing machine - it seems like he's just trying to talk to us most of the time. luckily, though, he doesn't usually do it all night unless there's something that's bothering him (someone shut their bedroom door or a cat outside or something like that).
