Performance notes
Cedarwood, rosemary, and peppermint oils are commonly used as natural insect deterrents in pet care products, and combining them in a shampoo format lets the oils work directly against fleas and ticks on contact during the wash rather than relying solely on a spot-on treatment. The dual claim of killing pests while soothing itchy skin suggests the formula is meant to address both the infestation and its side effects in one step.
