How do cats get fleas?
user
It’s pretty complex, but basically they can be picked up when a cat goes outside and comes in contact with rodents, and then from there the fleas can jump onto a human, and get onto their clothes.

They can bite you right but not live on the human?

Well, there’s a lot of things that might happen, it’s complicated, and even medical science doesn’t have an exact answer to your question. But generally a flea needs a blood meal from a cat to complete its life cycle.  Fleas usually don’t want to jump onto a human, but if they’re starving, they might bite you.

No, the flea has to live inside the human.  It can get inside by a cat scratch, but it can also lay eggs on a human’s skin and the human can just pick the eggs up that way.
