In it, they explain how one specific parasite found in cats can be potentially dangerous to humans, as well as many other animals. Toxoplasma gondii is one of the most common parasites in cats and is the specific parasite that is referred to in this video.

As they mention in the video, Toxoplasma is a common brain parasite that can affect humans, as well as cats. It is a very dangerous parasite, so you need to help keep your cat healthy, as well as your family.
