Whoever thought you could kill fleas with natural ingredients! Scratch is a wonderful concoction of chamomile, comfrey, calendula, eucalyptus, lavender, cedarwood, sage, rosemary and thyme. As if that weren't enough, a good dose of usnea lichen is thrown in for antimicrobial effects! That takes care of the fleas. To soothe and smooth your pet's skin: a four-oil base of cottonseed, soybean, palm and olive oils, in addition to shea butter and liquid silk. How's that for pet-pampering?
