[QUOTE=Catty1]Might be cheaper to use a Brita pitcher and filter for them? [

That was going to be my suggestion. It's what I put in my fur posse's fountain and they all love it. As for the itching, etc., do you feel little bumps on their skin? I know you think you've ruled out fleas but my Creamsicle has a skin allergy and she did the same thing and lost a lot of hair, above her eyebrows, too. We still don't know what she's allergic to but she gets a depo shot when necessary and is on prednisolone. Maybe your crew has an allergic reaction to the water or some new treats?
