Having been an outdoor cat in the beginning of my life, I was well aware of the nasty, vile little creatures. I can't think of one cat that enjoys having the blood-suckers eating away at them. The first thing my mom did when she brought me home was give me a bath and put some icky smelling stuff on me to rid me of fleas.
Now I don't have to bother with fleas too much. The humans sweep the floor often, add apple cider vinegar to our water, put stuff on the carpet, and put stuff on us to make sure we don't get fleas. Every once in a while there will be an outbreak since my older siblings go outside, but it doesn't get too bad.
