David, Your ferret's missing toes may be the work of an overzealous or first time mother. Missing toes, tails, parts of tails and even feet are somewhat common in ferrets. When jills clean off their newborn they eat the afterbirth. Sometimes inexperienced mothers get carried away and inadvertently chew off parts of their babies. Just one of the reasons its important to be with your jill when she is birthing. Cindy [Posted in FML issue 1065]
