Hmm this is all weird. Because have you ever heard of zucker rats? From what i hear a lot of big breeders breed all white rats to avoid any of them being zucker rats.
Look @ all of rodentpros rats, their all white. Iv never had anything but a white rat come from them.

"All the Rats that appeared to cause the main and most serious problems were all Black or Black and white and larges except 1 case of a medium white rat that was a very thick medium. "
"So from talking with Steph at Tinley Park they will not order anything that's not pure white.With another guy won't mention his name haven't cleared it with him.He will not use anything black or black and white this also includes his mice."
"So I will never order anything but pure white rats and mice from now on."
This is coming from Larry who lost many boas to this kind of thing. Me i keep quite a few boas. So hmm?
Im still not sure how high white rats cause this? And what exactly is high white? Am i looking to breed something with little to no white in them what so ever?
