The secret of successful flea control is to treat both your pet and its environment with effective products which kill the adult and the immature fleas. There are a range of tablets, injections, powders, sprays, drops and shampoos to destroy the fleas in your pet's fur. Not all products are equally effective and those you can get from your veterinary surgeon are usually much better than those sold in pet shops or supermarkets. Other treatments can be given to your cat by injection to prevent fleas breeding in your house.
