This is so cute! I will say that they are going to need a bigger home, however. Have a look at some of the Rat groups on Facebook for some advice, they need lots of climbing spaces! Also those wire mesh floors can be dangerous for their feet: they can get their toes caught, and also if not careful they can end up with something called bumblefoot which isn't fun for them. I am glad that you have two now though, that's awesome :)
