Drontal Cat Tablets provide effective treatment of gastrointestinal Roundworms and Tapeworms in your cat. Both Drontal Cat and Drontal Cat XL Tablets will kill every type of intestinal worm your cat is ever likely to get, and both will do so with a single dose, and without having to starve your cat first. The only difference is that Cat XL Tablets are specially formulated for cats 6kg+.
To avoid worms reaching maturity and affecting your pet's health, and to reduce public health risks, you should worm your pet regularly. Worming at least every three months with Drontal will reduce this risk, but ask your vet who will be able to evaluate your pet's health and your family's requirements and advise you on a specific worming routine for your pet.
Don't forget the flea control! Fleas are often infected with the larvae of the Flea Tapeworm, which can be transferred to your cat by swallowing the flea while grooming. So in order to control worms, you also need to control fleas. A spot-on treatment is the easiest way to protect your cat but you may also need one that kills flea larvae in your pet's surroundings, to effectively break the flea lifecycle.
If you don't control a flea problem at the same time as worming, your cat is almost certain to be re-infected.
