Okay kiddo, so let's talk about parasites.
Have you ever seen a tick on a dog or a flea on a cat? Those are both examples of parasites. Parasites are tiny living things that need to attach themselves to another living thing in order to survive.
They can be really small, like the ones that live in our intestines, or they can be big like tapeworms.
Parasites might make their host animal or person feel sick, tired, and weak, like you might feel if you had the flu. That's because they are taking away the things that the host needs to stay healthy, like the host's blood, nutrients, or energy.
Sometimes, parasites can be treated with medicine, like when you take medicine for a cold or the flu. In other cases, they might need to be removed by a doctor or veterinarian. It's important to keep yourself and your pets clean and healthy to avoid getting parasites!
