Why parasite protection matters for cats
Cats can be exposed to parasites both indoors and outdoors. Fleas, worms, mites, ticks and heartworm can affect a cat's health and comfort, with some causing serious illness if left untreated. Some of these parasites can also infect and cause disease in people. Consistent monthly parasite protection helps reduce the risk of infestations and supports cat health and wellbeing.
Cats can be exposed to parasites at any time throughout the year. Therefore, consistent monthly parasite protection helps reduce the risk of infestations.
