So I've setup my 1.3 breeding group of rats. They already seem to be pregnant =D now I enjoy having these little guys a little too much lol I find myself staring at them for hours lol.

So I'm trying to get them to tame down, they all seem to be very Interested in my hands, when I put my hand in they immediately Rans up to investigate. Doesn't really like being hold though.

However their enthusiasm is not all good while they come and investigate most of them will try to nibble my finger. I have wash my hands thoroughly and they still do it. It's not a bite it's gentle but still it's something I prefer them not to do. Any tricks?

Also if I just keep insisting on picking them up will them come around and nope be so squeamish in my hands?
