I have a mom here in the rescue that is a beige veriberk with a blaze and odd eyes. I believe this is considered high white and risk for mega colon? Am I correct? Also pretty much all of the babies in this litter have some WILD crazy markings. I am talking markings like I have never seen before. I plan to take some pictures as soon as I can for you all but I am been busy with 13 litters and now I am sick with a nasty flu/cold thing as well. But some of these rats are all white with a round patch over one eye. One looks like a ying yang with one half of his body white and the other black. A few have some HUGE wedge blazes on their noses/faces. Some looks like Black and White cows like you see on the happy cows commercials. I mean they are cute as heck but I believe that makes this litter extremely high risk for mega colon? I am looking for some answers. How soon would this present. Is there any kind of diet I can start them out on once they start on solid foods to maybe prevent it? How late can it present? Any advice or input would be appreciated. I have only dealt with one other mega colon issue in all of my years with rats and that was a late onset case, which was kind of odd.
