Parasite Makes Mice Sexually Attracted to Cats. UNO Is Using Citizen-Science to Understand If It Alters Cat Behavior Too.

Using Citizen-Science to Answer Questions.

Cat Behavior Research

In the cat-behavior lab, we are studying how the parasite Toxoplasma Gondii affects cat behavior. This parasite only reproduces sexually in cats, so cats are pivotal in its spread.

Many different infected animals are healthy, but the parasite has an amazing strategy to ensure its own reproduction: it alters mouse behavior so cats can easily prey upon them. We suspect it also promotes its spread by altering cat behavior. To test this idea, we are working with pet-cat owners so that we never infect cats.

Since some pet cats have been exposed to the parasite while others have not, we are comparing the behavior of these two groups of cats. This will help us answer whether this parasite manipulates the behavior of cats using a least-invasive, humane paradigm that is ecologically relevant.

Toxo Project

Toxoplasma Gondii is a parasite that infects many animals. Cats play a unique role in its spread.

Curiously, the parasite alters the behavior of otherwise healthy rats: Toxoplasma gondii infection affects the innate-fear response in rats and induces a fatal sexual attraction toward the scent of cat to make them more easily captured as prey by cats.

Our research wants to address whether the parasite also alters a cat’s behavior to influence how the parasite spreads between cats.
