Why do we have cat mothers, but not cats fathers?
There is a certain disease called toxoplasmosis, that we can catch from animals,
predominantly from cats, however other mammals can also
be carriers. The cat hunting for mice, birds and even insects, can become
infected with the unicellular parasite Toxoplasma gondii. The animal
itself does not suffer from this, but it does excrete many bacteria in
its faeces. In normal living conditions with a cat, it is almost
impossible to not become infected. In people this infection is usually
without symptoms and it is only people with weakened immune system (for
example as a result of AIDS, or immunosuppression, as well as pregnant
women) that such an infection can pose a problem.
In my opinion this is an example of tricking the host of the parasite for its own good. There are many examples of this kind of tricking in the animal world, some also in th plant kingdom, in which the behaviour of the infected animal is changed.
In this particular example the matter is obvious – the parasite does not do any harm to the carrier, but changes its personality in such a way that by building up friendliness and light-heartedness, the person becomes a 'cats mother'. And for men? As far household matters are concerned, they do not count, but as for becoming moody, they can’t be 'cats fathers' …
