Compare Profender spot-on worming products for cats by the exact pack's stated body-weight group, pack count and product information. Read the current Australian label for the listed parasites, suitability restrictions, administration, intervals and safety directions. A topical product should not be given the instructions of an oral tablet or another wormer. Ask your vet about an individual cat's needs or uncertainty about suitability rather than relying on a general three-month schedule, pregnancy or lactation assurance, or a category-wide gentleness claim.
