Yeahh, it might be true that I should have been a little more patient, but in the end I guess a rat colony makes more sense for me:
Fuzzies for the corn
Weanlings and sub adults for the ball
Adults for the BCI
I like to have rodents around me, but I am somehow limited in space...
If there will be a significant increase of scaly inhabitants in my flat, I guess I will think over it again, but by now I am quite certain there will be a Flowrock rattery within the next two or three month...
