Albino mammals generally exhibit a noticeably under-developed retina, with a fewer rod cells and central ganglion cell density about 25% lower than in pigmented animals. Many such baby squirrels have been rescued and fostered by a professional wildlife rehabilitator until they could be safely returned to the wild,[19] although the density of squirrel populations in many places and the constant care required by premature squirrels means that few rehabilitators are willing to spend their time doing this and such animals are routinely euthanized instead.
