I have 2 female,7 year old de-sexed Ragdolls. After allergenic tests for another complaint, my GP told me I have a very high allergic reaction to cat hair.I have had at least one cat as a pet for more years than I can, or wish to remember.The cats are staying with me simply because they are really and truly part of the family.I am not promoting any particular product here. But my Ragdolls are very happy that Claratyne exists and works
