Perceived parental behavior refers to the way of experiencing parental emotionality and control from the child's standpoint. It has been shown that children who perceive their parents as more emotionally warm exhibit fewer symptoms of anxiety, depression and social stress, have more confidence and develop closer interpersonal relationships. Family climate is defined as mutual support of the family members, their cohesiveness and emotional bond, and it is key to the success of the overall development of a child. It has been shown that children and adolescents who grow up in more favorable family climate feel stronger attachment to other family members. According to previous research, these two variables play a significant role in the development of the child's attachment not only to their human family members, but their pets as well. Attachment is a term that refers to a longterm emotional relationship of an individual with one or more significant persons, but also animals. It has been shown that children and adolescents spontaneously refer to their pets, specifically cats and dogs, as their close friends and social support. The aim of this study was to examine the relationship between perceived parental behavior and family climate with attachment to pets in high school students. 151 participants took part in this research (67 male, 82 female and 2 participants who wished not to disclose their gender). Mean age of the participants was 16.57. The data was collected via an online questionnaire constructed in the software Google Forms and the subjects filled out the Parental behavior questionnaire URP29, Family climate questionnaire and the Adapted Lexington questionnaire of attachment to pets. It was found that participants who perceived their parental support more favorably formed a stronger attachment to their pets. No statistically significant relationship was found between the attachment to pets and parents' permissiveness nor between the attachment to pets and parents' restrictive control. Furthermore, no statistically significant relationship was found between the family climate and the attachment to pets. Finally, the difference between high school students' attachments to cats versus their attachments to dogs was examined and the results show that dog owners are more attached to their pets than cat owners.
