The Hungarian linguists Katalin Balogné Bérces and Zsuzsa Szamosfalvi found in a preliminary survey of Serbian usage that the most commonly used "animal vocatives" were, in order, 1. pig, 2. chick(en), 3. dog/puppy, 4. cow, 5. monkey, 6. hen, 7. rat, 8. turkey, 9. mouse, 10. snake, 11. cat/kitten, 12. fox, 13. lamb, 14. vixen, 15. worm. Of these, using the classification devised by Sabina Halupka-Resetar, and Biljana Radic,[15] lamb was always used positively; cow and vixen referred to a person's appearance; pig indicated a person's eating habits; calling someone a fox or a turkey related to their intelligence, or lack of it; and names like cat, snake, worm, monkey, dog, mouse, chicken, lamb and rat were used to indicate a person's character.[16][17]
