Selamectin/sarolaner is a medicine you apply to your cat’s skin to prevent heartworms and other parasites, and treat and kill fleas and ticks.

While you can get worm medicine for tapeworms from your veterinarian, you also must treat all of your pets for fleas or you will soon be revisited by the “little, white grains of rice” again.

Even hairless cats can get fleas and ticks since the parasites feed on blood and don’t require hair or fur. Luckily, there are several effective oral and topical flea and tick treatments for cats.
