When I had my flemish giant peanut who passed away. I would use advantage for cats. It would keep the fleas & ticks away & worked like a charm! Whenever I would miss the next month, they'd jump right back on him... So I'd always have to be consistent.

Dose ranges from 6-18mg/kg. I always dose towards the 18mg/kg side of things due to many factors. Rabbits just need a bit more then a cat or dog, in particular due to their fast metabolism.
