Drontal cat wormer tablets are very effective as a single dose against most round and tapeworms in cats including dipylidium tapeworm spread by cat fleas. Drontal for cats will kill every type of intestinal worm normally found in cats. If your cat is a mouser they may be more likely to be infected. One tablet of Drontal will worm a 4 kg cat
kittens are not born with worm larvae already present, so worming does not need to start until 6 weeks old, with further treatments every 3 weeks, until 4 months old. Thereafter, worming at 3 monthly intervals should be adopted.
