This product contains spinetoram, a spinosyn-class insecticide that targets fleas, packaged as individual applicator tubes holding a single low-volume dose. The dose is formulated for cats and kittens weighing 1.8 pounds or more and at least 8 weeks of age, so multi-cat households do not need to track different products by weight class. Application involves twisting open the tube nozzle, parting the fur at the base of the cat's neck until skin is visible, and squeezing the liquid directly onto the skin. The formula is designed to be quick-drying and non-greasy once applied. Each tube is intended for a single monthly application, with protection intended to last up to six weeks per dose. Applicators should be stored in a cool, dry place and used before the printed expiration date. Packages are sold as trays containing one or more individually sealed applicator tubes.
