I would recommend a Dawn dish soap bath with warm water and make sure you dry Sally well. I would look for a product called Frontline Spray, which should be labeled for young cats. Once she is 6-8 weeks, talk to a vet in your area about topical products, like Revolution or Frontline Gold. I also recommend treating the house for fleas with a carpet spray. Remember to throw out the vacuum bag and treat the other pets in the house for fleas. Make sure Sally is eating a quality diet with the proper vitamins and minerals the help the anemia. If the anemia is severe, she may require a blood transfusion. Kisses to Sally!

    Although it would require going off label (most good flea products are labeled for 8 weeks and older) if the kitten had this degree of flea infestation I would consider using a product such as Capstar to kill adult fleas, then a product such as Revolution to get the fleas under control. In addition, of course, all other animals and the environment need to be treated. Sally should also be treated for tapeworms, which are carried by fleas. In very severe cases of anemia, a transfusion may need to be considered, so if she hasn't been evaluated by a vet I strongly recommend bringing Sally in. Hope this helps.
