Modern age aims its attention towards animalistic subjects both in everyday life and scientific and professional sphere. This is further confirmed by numerous specialized television and radio shows, scientific projects and gatherings, collections of literary works, various anthologies and books with animalistic orientation. Entire culture, including literature, is filled with various of animal species. All types of children's literature are brimming with a variety of animal species. Considering that animals are a common part of children's lives, this is not at all unusual. By analyzing animalistic dimension of Croatian animalistic novels, in this thesis we are striving to discover and confirm with examples different ways of showcasing animals and their meaning in children's lives. Some novels contain anthropomorphized animals that are more suggestive and expressive. Some examples are Don od Tromeđe (The Don of Three-border point) (1987) by Višnja Stahuljak, The wild horse (1989) by Boţidar Prosenjak, novels Mrnjau, they bite me (1976) and I have a tail (1976) by Kazimir Klarić, Branka Primorac's Love Case of Joja the Cat (1998), Dog reading from lips (2001) by Stjepan Tomaš and Dogs works (1995) by Ivan Tomičević. Other literary works realistic showcase compliance of animal and childrens' fates. This is the case in novels Pirgo (1953) by AnĎelka Martić, Mum, Beware of the Dog! (1993) by Branka Primorac and in Maja Gluščević's novels Story of the Deer (1982), Trap for a Bear Cup (1994), Escape in a Basket (1992), Ivo's Vučko (1995) te Piki and Argo (2006). Some of the analyzed novels such as Humandel (2007) by Hrvoje Hitrec and Dolphin Dirk and the Lazy Mare (1997) by Joţa Horvat display animals that under specific circumstances are able to communicate with humans. By studying Croatian animalistic children's novels one can notice the difference in representation of the animal world, in the way of communicating with each other and their relationship with humans, but also with members of their own species. What unites all of aforementioned novels is their contibution to Croatian children's literature, but also to lives of every reader, friend and lover of animals.
