Actually if you just pick them up by the tail then they are fine. Tongs REALLY piss them off and will just make them more aggressive. I have only been keeping soft furs for a few months but already through selective breeding I have soft furs that are almost pet quality. The one that is my favorite, the most unusual, unique soft fur that I have had will sit in my hand, not jump like some of the others do and actually likes to attention. And they can get expensive but I get mine at Critter Barn for $3 each. I do not recommend switching from rats to soft furs if you can help it. Yes they will eat almost every time and it is rare that my three balls do not eat, but soft furs take FOREVER to grow. In the time it takes to reach the size of a weaned rat, a normal domestic rat would be the size of a large and plumb small rat.
