Johnson's Hairball Remedy is a tasty malt-flavoured paste designed to aid in the elimination and prevention of hairballs in both cats and kittens. This complementary feed should be given between meals when your pet is hungry and not mixed with food. For adult cats, administer 25mm of paste daily for 3 days to aid elimination. Kittens over 4 weeks should receive 12mm of paste. The treatment can then be used weekly or as required. Please note that all measurements are manufacturer stated.
