I got my kitten at 7 weeks old and when I held him to give him kitty-lovin he would suckle on my ear lobe. Especially when he got up from his naps and when I got up in the morning. Now at almost 5 months old he's alot heavier and much more demanding for my ear. He hounds me until I let him. I don't let him do it anymore but he hounds me to no end for it. Is this normal.
