I went away on vacation to Florida for about 20 and in the mean time our neighbor took care of our cats. They are all indoor kitties and only had contact with her and she isn't sick. I come back and now two of them seem sick. They arent sneezing anymore than usual (the house has no carpet and gets dusty sometimes) but they sound congested. Is there any homeopathic remedies for cats to boost their immune systems so they can fight this thing off before they get sick? Thanks
