Humans are known to have their behaviour altered by a parasite carried by housecats, like this bug also manipulates the cat. Humans can either form depressive symptoms, or engage in acts and behaviour styles that allow the parasite to migrate to new organisms. Many housecats hold this parasite. Its role has long been underestimated.
Cat keepers should ask their doctor about it, and ask their veterinary to check their cat - regularly, if it is allowed to walk freely outside.
Cat loos have no place in kitchens!
Quite some evolutionary biologists say that they see the parasitical lifestyle to be the evolutionary most successful of all. - Life is not fair.
