Black Hooded Rats as well as Zucker Rats are specific Breeds.Specifically bred for scientific research into areas such as Hypertension,Diabetes,Obesity,other fat related health issues.So I can't say all multi colored rats are either Black Hooded and or Zucker. I can say that Black Hooded and Zucker are Black or Multi colored Black and white rats.You see the dilemma. I'm sure there are other multi colored black and white rats that are not related to Zucker or Black Hooded rats. You would have to know exactly where your breeders originated I think. This is why at this point I will stick with all white feeder rats and mice as well if or when I use them.

I'm not in a position to breed my own rats.



Two Links below have info about these rats I'm speaking of.

What and How these rats are bred for
