Hi, Donna! :-> I remember you from the soap lists! :-> I've made liquid soap for various purposes before. I buy an unscented liquid soapbase from www.soapwizards.com, and I add my own ingredients. For household cleaning, I like to add things like sweet orange essential oil (which can make the soapbase clump or respond strangely .. be prepared), or lavender essential oil, peppermint essential oil, tea tree essential oil, etc. The sweet orange essential oil is particularly helpful for things like cutting grease and cleaning litterbox messes (where you need some deodorizing/sanitizing properties). For a ferret shampoo, I prefer to add milder essential oils like lavender essential oil and/or tea tree essential oil. I add just a BIT of each of the above to the shampoo, with a touch of citronella essential oil. I rinse out the ferret VERY, VERY thoroughly before letting him/her go on his way again, too! You could also try adding the above essential oils to a shampoo like Neutrogena or Ivory or Dr. Bronner's liquid soap to make a mild "ferret shampoo", too. Good luck! :-> - Ela Ela Heyn Harborside Mail Stop 3024 201-860-3336 [log in to unmask] [Posted in FML issue 3048]
