Hi all! My two sons (age 10 and 7) and I have had our 2 rats for just over two weeks now. We sure love these little guys! Things are going well, mostly due to the great advice I read here! One little thing that is puzzling me is the little nibbles we get from one of our guys. Sometimes it is barely a graze, sometimes it's a little harder. He has never broken the skin but my youngestchild is pretty scared of him now :/ We've tried saying NO! sternly when he nips, also squeaking and I personally have tapped him on the nose a couple times but the kids can never remember to do it in the moment, and I tell them it is pointless to do it otherwise. I'm ot really sure where to go from here. If I find out it is completely normal and to just let him nibble w/ no consequences then I may be able to convince my scared child it is ok... but if the nips gets harder maybe not. Any advice???
