Very demanding little guy Milo is

Milo has now got to the point of trying to talk to me, his way of getting my attention. This happens more so when he see's a cup in front of me. He is a lover of anything in a cup that you are drinking.

Should he have a little coffee, hot chocolate etc. Personally I don't think so but at the same time, he can be very dominant and insistent, so what do I do, GIVE IN.

How can I stop this behaviour that he has recently acquired? If I say "no" he will go away only to return within minutes. Animals are very smart. He knows in the end he's the winner. Once he's had what little bit he wants, away he goes. If this is not acceptable or bad for his system please tell me what to do when he does this. I am certain there are others out there who have the same problem.

When eating meals he knows his boundary, he isn't allowed in the kitchen. However, coffee time in the morning is when he is most rambunctious. What can I do to stop this if it is against him and his digestive system? Help!!
