My kitten has fleas??? :(?

All his blankets that he uses, and the towels that you found some on, throw them in the freezer for a bit, and anything else that was touched.....also wash your floors with a carpet cleaner, and same with your couches and so on. But next time I advise you not to use dishwasher soap. Get a shampoo for kittens that is meant for flees, or just get a flee collar
