–Zoophilia is a disorder of sexual preference that is characterised by sexual fantasies or behaviours that include animals. Zoophilia is more common in comorbidity with other paraphilias. When reviewing scholarly publications, a small number of articles has been found that connect zoophilia, and other psychiatric disorders, and they are shown here. Out of the seventeen known to us isolated cases of patients with zoophilia in comorbity with other psychiatric disorders, nine are noted with zoophilia and psychosis. Precisely in those patients, and also in the case of our patient that we described here, we can speak of zoophilic behaviour as one of the signs of psychosis, although keeping in mind the small sample and the unreliability of data, it is hard to state that zoophilia is an early, or any other sign of psychosis. Considering that in our case zoophilia presented as an early sign of the psychotic process, it is for us to conclude how during noticing of such sexually deviant behaviour it is important to pay attention to all the other psychopathology as to get an insight into the possible start or exacerbation of the psychotic process in order for the treatment to be more directional.
