The cat with fleas is a host
While cat fleas (Ctenocephalides felis) and dog fleas (Ctenocephalides cannis) are two different species, most of the fleas found on dogs are actually cat fleas.
Fleas on a cat are probably either dog fleas or cat fleas (these are two different species, but despite the name, either can survive on either a dog or cat ... or for that matter on other mammals). Both of them can and will bite humans.
No, fleas will live in your home and bite people instead. Your home will need to be treated for fleas if a fleas are seen!
Fleas jump from host to host, so a flea can jump from one cat to another if bitten, but the bite itself will not cause the fleas.
No, a flea is a flea. There is no "cat flea" or "dog flea". Its just a flea and its just as likely to get a cat or dog.

Yes, fleas can make a cat ill because the bites can get infected
no
Yes, definitely. Fleas can infest almost any mammal. For example, I took my cat outside for a stroll, and a few days later I was itching like crazy. So was she. If you think you have fleas from your cat, I suggest flea bombing the house, flea shampooing your cat, and yourself.
There is a high probability that your cat will have more fleas on it. Fleas are tiny little things that reproduce fast, and your cat could probably have eggs or more fleas on it. If you want to prevent fleas, there are really good medicines out there you could use.
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.
