Revenge of the rodent?

I think it may have had fleas that it passed on to Mouse.

Because I woke up a couple of days ago with some small, itchy bites which I thought were maybe from a little spider, but now I have more of them. And spiders don't usually stick around to bite another day. I haven't seen any fleas on Mouse and he doesn't seem to be scratching, but I can't figure out what else could be going on.

Dammit. I really don't have time for this. And I'm scratching like mad, which is very undignified.
