What a nightmare I'm having with them. Firstly my youngest cat got them and then my other cat. I monthly. Flea treatment them and they still get fleas. Fleas have gone on my youngest one after much combing. Now my other cat won't stop scratching. I've combed her daily and it's much better but she's very itchy. I've given her a flea bath. I've treated the whole house and vacuumed daily. She's of to the vet Tuesday but anything I can do in meantime to soothe her. A friend said try benadryl but don't feel right giving it to her
