i dont go to petco but my local shop i went to to get feeders have no idea what african soft fur rats were, which was mildly suprising. i was kinda confused when i saw a 20 gallon tank a heat bulb and like 20 paper bags, when i asked what wa in the bag they told me it was their colombian boas. i dont know how good or bad of a setup that is but it was kinda weird looking and i know i wont buy one of those.
