No, we don't breed them! We have them just for fun.
They have a save place where the cats can't reach them.
Most of our cats are afraid of the tree girls anyway.
But Arnor thinks it's snack time when he spots them....and sometimes
we find him in front of the cage. But he must me careful,
because the ladies are trying to steel the long peaces of hair
between his feet for their nest.

No there not scary, rats are very smart and friendly animals!
If we ever find Norwegian Forest RATS then we will breed them :)
