According to Dr. Richard Ferber in his book "Solve Your Child's Sleep Problems," an 11-year-old requires approximately 9.5-10.5 hours of nighttime sleep.
I have read many times in book and in people's opinions and all have come up to 10 to 10 1/2 hours of sleep each night . Try not to get too much sleep , you might have a great morning but you will be tired by 4 , 5 at the most .
You should sleep six hours in the morning.
A preteen should get around 9 hours of sleep.
They should have 8 or more hours of sleep in a day.
They need at least 4 hours sleep plus. If they are still growing then it is advised to get 8 hours, but because of girls hormones when growing up this may agrivate there sleeping patterns. It is best to see when they are tired and need sleep.
if you mean how many hours you should sleep in a year it would be 3,650 hours of sleep for a regular year not a leap year
a cat shauld sleep 10-15 hours.

Well, it depends on your age. Adults should get 6-8 hours of sleep, while children should get at least 7-9 hours.
