Many people have used the kitten formula of Revolution or Advantage on their rabbits, with no problems.
You will also need to keep any area she is in well vacuumed. Fleas are only on the host at certain times, at other times they are in the carpet or rugs or upholstery. They need to be gotten up, along with any eggs they have laid. You should take the vacuum outside to empty the bag or cup, since the fleas could jump out back into the house if you do it outside.
One other measure to help you control the fleas, and to monitor if you still have fleas, is a flea trap. You can buy them or make one yourself. This wouldn’t solve an infestation, but it could help along with using Revolution or Advantage and vacuuming. Here are the instructions to make one:
How Flea Traps Work
Fleas are attracted to light. Positioning a light source over a container of water and dish soap or one lined with sticky paper entices the fleas to leap toward the light, whereupon they fall into the container and are trapped. Dish soap prevents the fleas from being able to stay on the surface of the water.
Flea Trap Receptacles
Any wide, shallow receptacle such as a pie plate, wide-mouthed bowl or baking pan can serve as the base for your flea trap. Light colors are better, because they increase the trap’s attractiveness to light-hungry fleas. If you’re using sticky paper, line the bottom and inner sides. If you’re using water and dish soap, make sure your container won’t tip easily, and add an inch or two of water and a few drops of dish soap.
Flea Trap Lighting
Position your light source directly above the trap, while making certain that it can’t fall in and create the danger of electrical shock or fire. Desk lights or clip lights can work well. You can also position your flea trap directly underneath a plug-in nightlight, or float a small tea light candle on the surface if you’re using water. For maximum effectiveness, the flea trap light should be the only light source in a dark room.
