I am looking to buy a calico. I have seen some for sale that are pretty low white. Do these get more white as they get older? If I get a low white calico will that produce mostly/only low white calicos? I have heard that it doesnt matter they will still produce a good range of low-high white calicos but I only heard this once in a different forum that I came across on the reptile report. I just want a little extra expert opinion on the matter. Thanks!
