Do cat fleas spread on people?

Fleas don't usually live in human hair but they sure do bite. So if you're living with a cat who has fleas be ready to wake up in the morning with red bite marks all over your skin. Sometimes fleas do live in human hair but as soon as they find an animal body they go there. Fleas produce 50 eggs a day and these eggs get into the carpets and floorboards and can hatch up to 13 years later ! So there are plenty of fleas to come on to humans too.
