Punish with active ignoring and withering looks.

Dear George,
Do you know what Costa Rica is or where it is? I’m asking because I found out that my human pets left for Costa Rica and will be back in about 2 weeks. I think it must be far enough if it takes them 2 weeks to get back home. So, I’m home alone with the human kitten who is now a young adult ….but he’s such a kid at heart; he loves me very much and plays hooky to spend time with me; we sleep late and best of all we eat junk food.
But that doesn’t mean I’m not angry with my human pets since they sneaked out the house and off to Costa Rica whatever that is. I have planned how to punish them but I’d like your opinion and suggestions too. Here is my plan: when they come back I’m going to isolate myself in this limited space as per photo attached. I planned to ignore them completely and I’m going to refuse food. Since I was on junk food (with the human kitten) I never had to open a can while they were away so I’ll make them believe that I missed them so much that I wasn’t eating! I want them to feel guilty, guilty, and guilty!   
But, George, how long can I stay without eating? I heard cats can’t be without food for more then 12 hours. Is that right? Ugh! I hope I don’t need to starve myself for such a long time. I just hope that my human pets have some common sense and will feel guilty in the first hour.

Dear Victoria,
Not eating.... well it will worry your humans, no doubt. But it's a strategy that is punishing for you as well as them. I wouldn't do it, Victoria. Cats that have a cat flap can do this more easily because they can just saunter down the road and break into a house to eat another cat's food. Or just find themselves another human feeder. But you can't do this and you are used to regular meals. 
Putting yourself in an isolated space and refusing to acknowledge your humans is a much better idea. Refuse to share the bed with them at night - instead go to the young adult human's bed. Stay away from any shared armchair and absolutely show your dislike of their laps. If you have to share the same room, turn your whole body away, look away from them, and make it clear you are thinking of higher thoughts.
Just to punish them a little further. Lavish affection on the young adult. Leap into his arms, cuddle up on his lap, purr loudly in his ear. You love him so much that you don't care a fig for the humans that abandoned you for a whole two weeks. 
Also don't forget the withering look. We cats do a wonderful slow withering and contemptuous gaze when we want to put humans in their place. JDI. Just do it. It makes humans feel small.
Hugs
George
PS. For UK cats reading this, be careful when you go out in the snow.  Rock salt put on the roads to get rid of the snow is poisonous. So if you get it on your paws, ask your human to wash and dry them on your return. 
PPS. Very pleased by comment below on being a whisperer. Shall update my profile immediately.
