Fleas

I made a discovery of fleas on the cats last night. I am not sure how they got infested with these little pests as they do not go outside. I got some stuff today to treat this issue. I got some spray to kill right away, some shampoo to get rid of the carcasses and some drops that will keep them away. I sprayed the little bastards tonight, something that they cats really enjoyed. I thought I might lose a couple of fingers. I can't wait until I give them their baths tomorrow, that ought to be pure fun. Since I made the discovery I have felt like things have been crawling all over me. I know that fleas don't particularly like humans, but you know. Well, the problem should be taken care of so I won't have to worry about it. I would like to know how it happened though. The only thing that I can think of is I brought them in on my shoes as there are alot of rabbits running around the area.
