Worms and parasites

All cats should be regularly treated for both roundworms and tapeworms, as these are very common in cats. In some countries, cats will need to receive treatment to prevent heartworm infections too. Frequency of worming should be based on a risk assessment for each cat. Cats with outdoor access should be dewormed at least every three months and cats that share homes with children under 5 years of age or people with a compromised immune system should be treated monthly. As with flea treatments, a wide range of wormers are available for cats, so it is always best to ask for advice from your vets.
