Sorry if this has already been posted...

I really REALLY want to add a pair of hairless rats to the family, this time I want to do it the right way and get them from a rescue because my petstore that is respectable doesn't carry hairless rats because there isn't enough demand for them. So rescue which is obviously the best choice though farther to travel is what im looking at. First of all, is there anything specifically different in the way one would care for a hairless rat? and Second of all, has anyone had problems with rescues in the past?!
