Just to dispel two myths, rats can have chocolate just not too much. That is what they use as rewards in labs for behavioral study. I have also given my rats chocolate, the only issue with it is if you feed them too much they will get very fat and they also get very hyper from the coca in chocolate so feed small portions one a month I say.
Also rats dehydrate easily, they can't go long without water. I would say past 24 hours their bodies will start to dry out and they can even die within 24 hours with no water on a hot day. Rats are actually found near water sources more than in deserts unless they are a desert breed. NR (common brown rat also the fancy rat) can't go long without water. Sorry to get off topic just making that clear so no one thinks a rat can go long without clean fresh water.
Also the common brown rat isn't native to Europe, they are native to Asia (China at that). They didn't arrive to Europe in full swing until shortly after the first burst of black death so around the 1700's (And yet they still blame rats...T.T). First domesticated in the 1800's by Jack Black the queens official rat catcher her caught rats for pit dogs (they put rats in a pit and had dogs kill them) but the more beautiful colored ones were bred, tamed, and sold as pets to those in high society. It wasn't uncommon from a woman in high society to be at a party with an albino rat on a monkey leash in her lap.
