How many drops of tansy should be used for cats to treat fleas? - briefly
Use 1–2 drops of tansy essential oil diluted in 5 ml of a pet‑safe carrier oil, applied to a single spot on the cat’s back, and do not exceed a total of 3–4 drops per treatment. Repeat no more than once every 48 hours, monitoring for irritation.
How many drops of tansy should be used for cats to treat fleas? - in detail
Tansy (Artemisia vulgaris) can be employed as a natural flea deterrent for felines, but dosage must remain within a narrow safety margin.
A standard tincture prepared at a 1 : 5 ratio (herb to solvent) is the recommended form. For topical use, apply 0.5–1 drop per kilogram of body weight, with an absolute ceiling of 5 drops for any individual cat.
Example calculation: a cat weighing 4 kg receives 2–4 drops; exceeding five drops increases the risk of toxicity.
Before application, dilute the measured drops in a carrier such as warm water or a mild pet‑safe shampoo. Distribute the solution evenly over the coat, focusing on the neck, base of the tail, and underbelly where fleas concentrate.
Administer the treatment once daily for a period of 7–10 days, then reassess the infestation level. If fleas persist, a repeat course may be initiated after a seven‑day interval, never exceeding the maximum daily dose.
Observe the animal for signs of irritation, excessive salivation, vomiting, or behavioral changes. Immediate discontinuation and veterinary consultation are required if any adverse reaction occurs. Pregnant, nursing, or very young cats should not receive tansy preparations.
When toxicity concerns outweigh benefits, substitute with veterinarian‑approved flea control products.
