Koera keele otsas rohi, kassi keele otsas tõbi

Abstract

The above proverb is found in the database of Estonian proverbs in different variations 160 times, making this the second most widespread proverb about cats and the fourth about dogs. The article outlines the roots and background of this belief, viewing the behaviour of both animals and their habits in co-existence with humans. This kind of differentiation between cat and dog is rather a reflection of people's accustomed behaviour and expectations derived from the animal's behaviour - both animals' mouths contain both pathogenic micro-organisms and healing substances.
