What spiffy varieties do you have?

[SatanicIntention]

Only shady pet rat breeders, who have no concern for the well-being of their colonies, get rats from pet stores and introduce them into their existing lines. Fancy rat breeders take great pride in their rats and the established pedigrees they have molded over years and years of selective breedings. If you want to get rats from breeders and breed them, then by all means, be responsible about it and GET PERMISSION(not likely). But DO NOT ruin those breeders' lines by going and getting "pretty" pet store rats that "you" may feel are good quality(when they're not whatsoever) and breed them into those existing lines. That's very disrespectful and irresponsible.

Ask ANY GOOD breeder, such as Bellaratta's Nest in Florida, Cammarattery, SkyClyde in California, Alpha Centauri in UK, and quite a few others, would NEVER go get a "pretty" rat from the pet store and use it for breeding.

And I'm sorry, but unless you are a laboratory wanting to experiment on said True Hairless rats, then there is NO possible way for you to obtain True Hairless (athymic) rats.

I also wasn't talking about hairless CARRIERS(haired rats that carry the gene for hairlessness). There is a big difference. I'm talking about hairless rats, not double rex. Double rex don't seem to have the same problems, or at least as often.
