Wow I can't believe the hair growth on them so quickly! Very cool Heath! Me being a nut about rat breeding of course there's going to be a ton of questions here LOL.

Why use these over the more traditional domesticated rat? How are the temperments of the adults you currently have? Any difference in husbandry, hardiness or litter production? Are they known to be good parents as domesticated rats are usually i.e. is the male safe with his young? do the females generally accept their young readily? Any known difference in acceptance as a prey item by snakes? Can one feed some of these and some domestic rats or has this ever been tried to your knowledge? What is the difference in size at maturity and do they reach larger sizes more quickly? Are the stages of growth as nursing young comparable to domesticated rats or are they larger/smaller or quicker to pass through those stages to weanling size?

I know I can find some of this with research (which I will be doing tonight) but I always prefer some first person information/actual experience as well.
