Profender Allwormer Large Red is a spot-on intestinal worming treatment for cats, applied directly to the skin at the back of the neck to eliminate the need for oral tablets. The red packaging indicates this formulation is for the large cat weight range, and the spot-on format is absorbed transdermally without requiring any cooperation from the cat.

Profender's active ingredients — emodepside and praziquantel — treat and control roundworms, hookworms, tapeworms, and lungworm in a single application. Applied every three months, it provides quarterly coverage against the intestinal worm species most commonly found in Australian cats. Safe for kittens from 8 weeks of age, the spot-on format absorbs quickly and is gentle on the coat at the application site.

Spot-on wormers exist largely because cats resist tablets — and most do. The three-month treatment interval keeps the schedule manageable, and the single-application format means no pill pockets, no hiding medication in food, and considerably less stress for owner and cat alike.
