I definitely feed him enough food and he is a healthy weight. He drinks normal amounds of water as well. But everytime I make food or sit down to eat he's all up in my business sticking his face on my plate. I never ever give him any "human food" while I'm eating because I don't want him to development bad habits but he still won't let me eat in peace! Sometimes I have to keep him in a separate room so I can eat without him jumping on my lap. What can I do about this? Is this normal cat behavior?
