Thanks for the pic! Apparently my sexing skills are worse than I thought. I ended up with 3.1 hairless, so I'm keeping 1.1 of them and going to do a test breeding when they are old enough to see if the female can produce milk and care for a litter. I still don't care for their looks much, but it would be good to know if this line of hairless can produce milk or not. Apparently no one within 2-3 hours of me wants hairless rats (there are loads of people looking for them in the northern part of my state, but not near me).. So the one male I don't keep for breeding will probably be euthanized and used as a feeder.
Your female has nice markings btw! I love blazes on rats.
