Now that the terribly dry winter air is back, Mitties has been very itchy (and me too!). I don't see any dandruff; her hair is very sleek and soft and I think that's due to her high quality food, but she's stratches herself a lot, particularly her face and back of head. She has been drinking more water and I've been running the humidifier, and we're both miserable. I can use lotion to quench the skin, but what (if anything) can I do for Mitties?
