The-Sun: A new study indicates that cat owners are seen as better looking and have more sex. The same study found that women who are infected with a parasite commonly caught from felines, had 63 per cent more flings. They were also thinner and seen as healthier. Both men and women carrying the bug Toxoplasma gondii were perceived as more attractive. Scientists believe the tiny parasite subtly alters hosts’ behavior — possibly through its effects on key hormones – to increase the likelihood of being passed on.
