I think the mom & dad rabbits have fleas, too. How soon and with what do I treat rabbits to rid them of fleas. Is there any other thing I should get for them like shots / vaccines? What kind are those?
There is a natural product called diatomaceous earth, which when applied very carefully, in small amounts to the rabbits, will kill the fleas. The reason I say apply carefully, and in small amounts, is because it can be terribly dusty. Your best bet is to use a plastic bottle, and poke holes in the lid. Make sure that you buy hunan grade diatomaceous earth. After treatment, I would put the bunnies in another cage, away from the other one, and take out all bedding and feces from the old cage. Sprinkle some of the earth all over it and then put back some clean bedding. Just make sure you don't create a cloud of dust. If you've had the bunnies in the house, vacuum and vacuum again.
