Cats Are 'Likely' Spreading A Dangerous Parasite Across Canada Says A New Study
It can also infect humans, too.
A study from UBC has found that free-roaming outdoor cats are likely driving the spread of a parasite to wildlife.
The study said that it's likely the cats that are wandering around freely outdoors that are to blame for the spread of Toxoplasma gondii, a parasite that researchers say is potentially deadly.
The study analyzed 45,079 cases of the disease in wild mammals, making it the first study to look at so many species on a global scale.
It said that the disease is linked to chronic conditions like types of cancer and nervous system disorders.
The parasite can infect birds and mammals, which include humans. According to the findings of the study, the parasite is dangerous for pregnant women and anyone who is immune-compromised, adding that it can cause serious illnesses and even death.
In a healthy mammal, though, the parasite remains dormant.
The parasite is more likely to infect in places with a high human density, like urban areas. With more humans come more pets, meaning that an increased population leads to more free-roaming cats that can spread the parasite.
Cats have a unique ability to quickly spread the infection. "One infected cat can excrete as many as 500 million Toxoplasma oocysts (or eggs) in just two weeks," said the study.
These eggs can live in soil and water for years before infecting something.
With the finding that cats are most likely responsible for the increased likelihood of infection near urban areas, it makes it easier to reduce Tocoplasma in wildlife by limiting roaming cats.
The solution? Keep cats indoors as much as possible to help reduce the spread.
