I've noticed that all the rats I feed off never bite even if they have the chance. Feeding my butter female today, she wrapped around the lower half of the rat giving it free reign to get nibbled on. The rats mouth was pressed against her, so I quickly grabbed the rats ear and pulled it's head back (yes I know, i need to start prekilling my rat. that has to be the most suck death) and realized it wasnt even trying to bite. So are they just to dumb at that age? Rat weighed about 87g. Just curious.
Thanks
