Not every cat owner wants a synthetic insecticide on their cat's skin, which is the gap a plant-based repellent like this is built to fill, even though the trade-off is usually a shorter protection window than a conventional treatment.

This spot-on contains Margosa extract at 5.0% w/w, ethyl butylacetylaminopropionate at 4.9% w/w and eucalyptus citriodora oil at 0.1% w/w, applied by parting the fur at the back of the neck and emptying the pipette directly onto the skin. Beaphar say it repels fleas for up to 4 weeks per application - 12 weeks of cover from the 3-pipette pack - and it's reapplied every 28 days, with a minimum 7-day interval between applications. It's for cats from 12 weeks old, at any weight.

On the word "repellent". This is described as a repellent rather than a killing treatment, and it's plant-based rather than a conventional insecticide - if a cat already has an established flea infestation, treating the home environment as well is part of Beaphar's own advice, not optional.

Who it's for: owners of cats over 12 weeks who'd rather use a plant-based repellent as ongoing prevention than a synthetic insecticide, and are prepared to reapply on a strict 28-day schedule.
