He's not that much of a big eater (compared to the other one that won't leave the kitchen!) and even after eating he'll run upstairs and start meowing. Saying that he, does it everywhere not just upstairs.
And with a family of 5, he tends to meow for me more. This is because I lay on my bed with a laptop playing games, he comes and sits between me and laptop or on the keyboard if I let him. So when I'm not there, he sits at my bedroom doorway yelling at the top of his voice. Its so loud, we've had people who were outside ask us what the noise was as it doesn't sound like a meow.
Not sure if he has an Siamese in him. He's pure black in colour. Hes a sweetie, his name is Merlin but is far from being magic making that racket!
Cheers for your help guys, think its just gonna have to be the kitchen for him!
