rats to fleas, fleas to humans, then human to human
If the inscet has a sickness they can pass it to us.
Yes, any animal with fur can.
In medieval times (when the black plague was at it's fiercest people did not understand that the black plague was caught from fleas but thought it was an illness from Lucifer/satin/the devil. The medieval people thought the sickness would stop being contagious after the bodies were burnt. Unfortunately for them the fleas had fled the body long before it was burnt thus creating more sickness and death.
Fleas can transmit heart worm, tapeworm, etc. to your animals. Fleas are tiny, but they sure can pass things on to your animal that you wouldn't want. The best thing you can do is always keep up on the flea treatment and preventatives.
Well, fleas use to carry the bubonic plauge which killed 1/3 of the population in Europe that won't affect cats/dogs. If your /dogshas had fleas for a while it can become allergic to a flea bite and heavy infestation can cause annemia. but the chances are it will just cause the cat/dog some discomfort!
The main carriers of the bubonic plague were fleas and rats. The fleas got it from the rats when they bit them. When the rats died, the fleas went to new hosts, bit them, and gave them plague in the process. Usually the new host was another rat, because rats hang together, but sometimes there was no rat to go to, and the fleas went to whatever animal they found.
A flea may get on a person, but they do not infest them. Also, hamsters do not usually get fleas. If they do, you will be able to visably see them and pick them off with your fingers. If they are scratching a lot, it is more likely that they have mites.

I do not have fleas, but it is possible for humans to fleas. Usually though fleas stick to dogs and cats etc.
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 rabbit are just called fleas, and a rabbit with fleas is just called a rabbit with fleas. If your rabbit has fleas, the safest way to treat it is to take the rabbit to a vet.
