What is the minimum amount of water and food for a 14 year old .....?

Question

He had surgery last week and is thin to begin with .
I think it is part rebellion and part pain.

He is ready to go to the hospital for dehydration based on what he has refused to eat or drink for two days.
He over-heard me and now ate 1/2 sandwich and 8 ounces of water. He may be on a roll because he does not want to go to the hospital. I do not want to drag him out if he is having enough now.

WHAT AMOUNT OF H2O AND FOOD IS THE RULE?

Answer 1

You need atleast 8 glasses of water a day, but men should drink atleast 13 cups.
For food, I would recommend eating atleast 2 foods with grain a day, but if he's loosing alot of weight, perhaps 4.
Eating so much fruit a day is reallu healthy too, an orange or a banana will do.
But, to really answer the food question, there really isn't a limit to how much you should eat unless your going over board or eating too much

Answer 2

I personally do not recommend a ferret as a pet for a child (or young teen). They require a lot of care and attention - and lots of cleaning. They poop a LOT. And it's not nice little pellets like rabbits make. You say that you can spend the time now, but think - what will taking 2 hours out of your day do later on when you are in high school, doing club things and sports, and hanging out with friends? Ferrets can live for 7-9 years on average. When and if you go to college, you will probably have to leave your pet at home for your parents to care for. Is this something they would be okay with? They can also get to be very expensive. Cage, bedding, food, toys, veterinary care, etc. can really add up quickly. Have you considered ferret-proofing? They can get into anything and everything - inside and under the smallest bits you never imagined. They can foil upholstered furniture, squeeze under the fridge, find holes in your cabinetry... Don't get me wrong, ferrets are wonderful creatures - the silliest, most fun-loving animals on the planet. They make great pets, but not for people who can't take the responsibility, or can't handle the stress of such needy animals.
