That's funny you should ask that now. I just brought a new kitten home the other day and a friend of mine noticed he had fleas. I wondered the same thing but I haven't found any info yet about getting fleas off snakes but plenty about mites and ticks. This makes me think fleas don't infest snakes. I don't know for sure though. I certainly hope not. We've had mites on the snakes once and it was a giant pain in the *ss, as I'm sure many others know. I sure don't want to go through that again.
I feel a little light headed... maybe you should drive...
