I've gotten quite good at imitating Remus' meows. When he is being friendly, his meow is short. I find that if I meow back he takes it as a sign for him to headrub me and cuddle. If his meow is long *meeeeooooow as opposed to a short little mrow* it is a sign he is agetated (he usually is out of food or water when he does this but he'll yowl if I don't have my bedroom door open or if I lock him out when I take a shower. He also yowls if he gets too wet. He'll escalate to yowling too if I don't respond to his quick meows.) Impatient kitty! I notice too Debbie, that if I lay down on my back Remus is generally up in my face (even when Im playing a game ).
