I just read the care sheet we have here, I still have to contest the ASF = low odor rules...

I smell them after a week, and their odor smells worse than domestic rats IMO after that week has passed. (it wasn't bad when I only had 3 weaners! )

It's not a strong over powering odor that can be smelled throughout the rat room, but standing over their tank/tub and it smells nauseating.

Not over crowding, use pine pellets, feed Mazuri, have lots of fresh water... so who else can smell them besides me? I think I'm the only one...
