CAT owners are thought to be better looking and have more sex, research shows.
One study found that women infected with a parasite commonly caught by moggies had 63 percent more affairs.
They were also slimmer and considered healthier. Both men and women who carried the Toxoplasma gondii beetle were perceived to be more attractive.
Scientists believe the tiny parasite subtly alters the host’s behavior — possibly through its effects on key hormones — to increase the likelihood of transmission.
Having more sexual partners increases the likelihood of the bug spreading.
It’s thought that up to one in three Britons suffer from toxoplasmosis, most commonly from used cat litter. However, most people are not aware that they are wearing it.
Previous animal studies have shown that this leads to behavioral changes, e.g. B. that infected rats are not afraid of cats, so they will be eaten and pass them on.
Researchers analyzed data from 213 adult humans, with those infected turning out to be a third more attractive. They also appeared to be a fifth healthier than the uninfected.
Women with the Beetle also weighed ten percent less.
It is unclear how it affects humans. But one suggestion is that infection disrupts genes that control the production of the “happy hormones” serotonin and dopamine.
It can also affect attractiveness by increasing testosterone levels in men and decreasing them in women. Another theory is that infected individuals burn more calories.
The results were published in the peer journal PeerJ.
Lead researcher Javier Borráz-León of Finland’s University of Turku said: “The parasite can produce changes in the appearance and behavior of the human host, either as a by-product of infection or as a result of manipulating the parasite to increase its spread to new hosts.”
