Your cat might have worms without you even knowing about it. The two main types of intestinal worm affecting UK cats are roundworm and tapeworm and symptoms aren’t always easy to spot. Intestinal worms can easily be picked up by your cat e.g. from eating microscopic worm eggs from the environment, from hunting or from swallowing infected fleas when grooming. Kittens can even pick roundworms up from their mum when they suckle her milk. Highly effective against all types of intestinal worm commonly found in UK cats, Drontal Ca tablets can be given with or without food and work quickly to combat worms in your cat. It is recommended that an adult cat is treated for intestinal worms at least every three months. However, there may be situations when more frequent treatment is necessary, for example if your cat regularly hunts, monthly treatment may be recommended. Speak with your vet regarding suitable worming frequency for your cat.
