No, i live in Alaska there are no rats. this is the only place in the world that doesn't have rats. We keep our ports and borders clean from rats so they can't get in here. We don't have deadly spiders or snakes either.
If they are pet rats kept in a clean cage, then you can't catch anything. Otherwise they may have fleas.
They're about as dirty as the average dog. If you clean your rats cage, house, toys, etc, every week, feed them a good diet & groom them, they can be very clean indeed. Rats spend a lot of time grooming themselves, & are actually cleaner than cats.
No, rats never carried plague. It was the fleas that they carried. Domesticated rats don't have fleas. Even wild rats are very clean and any fleas they do have don't carry plague much anymore.
Yes they stay stinky if you don't clean their cage.
I don't know, maybe because of the wild rats. The wild rats are nasty, and spread diseases, but then people add that detail to the domesticated pet rats. I think pet rats are very clean, if you take care of them. Hope I helped ^^
