When my daughter got gum in her waist length hair I used oil to get it
out. I soaked the hair in oil (around the gum) and then pick it out a
little at a time. It took ages, but it works. I've also used an ice
cube to freeze the gum and break it off in little pieces, but I don't
know if a ferret would tolerate this.
