@Julez: They walked all over me yesterday :D I had to entice them but still, it counts xD One of them is so meek she just wants to sit in one place and be petted. The other one is a troublemaker.
I did put Cotton in their cage and she wasn't panicking (even stole some food, lol) but she wanted to leave after a short while, though it was still longer than when she's with them there.
But then she was kind of agressive towards the bolder little one... Not too much but when they're in cage and Cotton's running, she waits for them to come closer and obviously wants to bite on them. A big no-no. So I googled joining rats (don't ask why I haven't done that earlier, I have no clue and I'm
ashamed 
) and I realized we did some things out of order and probably messed some stuff up, but I hope it's still fixable

For a few days I'll just slowly start mixing their scents by mxing their litter (I hope that's the correct word for it lol) and getting Cotton in the youngesters' cage while they're gone and putting them in hers while she's gone. We'll see how that works out. Pray for me
I can tame new rats just fine, but joining stranger rats is not my forte...
@River: Omg, what's going on in the world? People are out of their minds or something? They choose all the stupid people to be their leaders

There's some major global fuck up going on...
I personally think people should be penalised with a fine for not voting and that fine should increase for every election you don't vote in. Unfortunately I'm afraid this would not help with the fact that the majority is stupid and easy to manipulate etc...
Geez, I'm so bitter XD
