Play fighting?

Okay, I posted about this before but I feel more needs to be asked. My two are still scrapping a bit, Remy always seems to instigate it. There hasn't been any blood nor is there excessing squeaking but they do do it a lot. They also don't seem to spend a lot of time together and so far generally sleep in diametrically opposed corners of the cage with very little interaction even when awake. Are they actually not getting along or are rats just like this?

You could try popping them in a carrier and taking them for a ride, as their group has been split from 4 to 2, they are working out who's boss, and until they do this they will excessively play fight and might be a bit uppity with each other till it's sorted.

They just need to bond a bit more perhaps?

When I went in this morning they were sleeping together and loked like they had been for some time, which is good they usually won't do that for more than 5 minutes. The thing that makes me surprised that it's still happening is that Remy always initiates it and Emily hasn't really shown any sign of caring, she'll run off or push her away if she keeps doing it but generally she sees to be being quite submissive...

I am sure it will calm down soon on failing that camomile tea helps calm
