I've heard some people quote that their ferret is a Marshall tattooed ferret. Is there an explanation behind these so-called tattoos? BTW, my newly adopted sable ferret, Roscoe, has 2 black-dot tattoos in his right ear & I was curious what does that mean? The tattoos are markers so you know that you have or are adopting a Marshall Farms ferret. You may also find a tattoo between their toes, that will indicate which doctor neutered/spayed them.
