Heartworms in cats are no fun. Flown in courtesy of the ever-loathed mosquito, these insufferable parasites hitch a ride in their proboscis, where they can make their way inside your cat after an unlucky bite. From there, the heartworm wriggle their way down into the innermost workings of your cat, growing up to a foot in length inside their lungs or heart!

Not only are they a gross and alien concept,  but they can also do some serious damage to your cat's wellbeing.
