Yes. It's very important for rodents to groom themselves or each other, as it helps to keep them clean and healthy.
yes that is natural care for its self its like you taking a shower
It is a very good thing when a rat grooms. It means she/he is comfy in her/his new home. ( And it's also like taking a bath for them.) Also, if your rat falls asleep on you or almost does then it means that you bonded so keep it up!
The only thing you can do is take it to the vet. It sounds like your rat has an Upper Respitory Infection. It will not heal by itself, it is not like a human cold. If left untreated, your rat will eventually die from this.
A rat is a living thing
to have a baby rat
I have a rat and he is quite cleanly, he grooms himself but I also give him baths with mild kitty shampoo. But they will not be very clean if you don't clean their cages. Yes they are pretty clean :) I LOVE YOU FLOYD! WOO (Floyd is my rat)

Of course not !
No, "Rat School" would have to be a myth. At least, that is what i think.
They definatly can be. My rat is an albino, and she's the sweetest thing in the world.
