Then, the researcher gave the patients face-to-face, individual information about hand hygiene after contact with a live cat for approximately 15 minutes in the waiting room and offered them a "Live Cat Information Brochure." Patients were then asked to spend 20 minutes with a pet at home twice a week for 12 weeks. "Edmonton Symptom Diagnosis Scale" and "Oxford Happiness Scale Short Form" were applied to this group of patients three times: before, at the 6th week, and at the end of the 12th week of the study.

Before starting the study, the "Structured Patient Information Form", "Edmonton Symptom Diagnosis Scale", and "Oxford Happiness Scale Short Form" were applied to the patients. Treatment was given to this group of patients only after informing them about the study, and the patients were followed for only three months. "Edmonton Symptom Diagnosis Scale" and "Oxford Happiness Scale Short FormS" were applied to the patients three times: before, at the 6th week, and the end of the 12th week of the research.

The patients were allowed to spend time with an animal (cat/robotic cat) for 20 minutes twice a week for 12 weeks.

The scale includes "pain, fatigue, nausea, sadness, anxiety, insomnia, loss of appetite, the feeling of well-being, shortness of breath and other problems (changes in the skin and nails, sores in the mouth, numbness in the hands)." Sadırlı and Ünsar added other problems to the scale. Therefore, the current version with 11 items was used in this study. The severity of each symptom ranges from "no symptoms" to "very severe," with increasing numerical intensity between 0 and 10.
