I know I'm late on this one, but I'd like to say that Revolution works great and PLEASE get a correct dose from your vet based on your rat's weight. Also, a second follow up dose in 2 weeks is a good way to go as a back up measure. And definitely do the bleach thing with the cage, all toys (throw away wood or paper toys that cannot be bleached safely), wash all food bowls and water bottles in the dishwasher, if not doing so already. Then do the bleach thing with the cage and toys again in 2 weeks. Then you can breathe easy that all the little buggies are gone, gone, gone!!
