I have a new cat from the Humane Society that was once a street cat. It's about a year old and it wont stop meowing whenever it knows there's a human around. I've had it about a week and have kept it in my room, as per the humane societies recommendation. When im in another part of my apartment and I am quiet, it will eventually stop meowing. When it's on my lap or sleeping it sometimes stops meowing.

Essentially, if it knows someone can give it attention it will scream and scream. I let it out of my room once and it ran to center of each other room , one after the other, screaming loudly.

I purchased Feliway about 4 days ago to help with the transition but so far no luck.

What can I do to keep from driving myself and my neighbours insane?
Will the cat always be this noisy and needy?
