I am starting to raise my own rats and was wondering if it would be okay to mix different litters. All the litters are going to be related because they will all come from just two rats. A few scenarios:
1. Say two rats have a litter and after the kittens are weaned I will put them into another tank (and yes males and females seperate tanks). Now if those two same parents have another litter could I mix them with the rats from the last litter?
2. Say two pairs of rats have kittens (and they would have the same grandparents (if that matters)), now will each litter be able to mix together once they are weaned?
I just don't want these rats to fight if they feel like the rats are intruders.
