I greatly appreciate everyones input. I got gloved up and checked out the "infected tub" which is now the we're in "heat" tub. I combed through their fur and didn't find anything, honestly they're amazingly clean. The only place I found anything on the "infected" girl was just around the bald spot which seemed to be stuck scab and it rubbed right off. The other two in the tub are spotless under and in their fur. I'm gonna keep my eye on um for a few days before I go feeding off anybody.
