This survey was the first one investigating opinions of veterinary students in Croatia towards companion animals and their welfare, with special reference to dogs and cats as the most popular companion animals in the European Union. The study included students of all six years of the integrated undergraduate and graduate veterinary medicine study programme in Croatia. First-year students were surveyed twice, before and after having attended the course on animal welfare. Student opinions were assessed on the basis of their mean responses to five-point Likert scale questions and frequency of responses to Yes/No/I do not know questions and ratio scale questions. Study results revealed students to have strongly positive opinions towards companion animals and their welfare. The majority of student statements did not differ significantly between the first and sixth study years or before and after having attended the animal welfare course in the first study year, mostly yielding a straight, non-fluctuating line. Students were not sure whether welfare of companion dogs and cats was compromised. Study results pointed to reliable and reasonable opinions of veterinary medicine students in Croatia towards companion animals and their welfare, as well as to the welfare issues these species may be facing nowadays.

Air quality in zoo premises is insufficiently investigated, yet scientific interest is growing. In these places, air pollutants such as microorganisms may represent health risk for both animals and exposed people. Thus, maintaining good air quality is crucial for ensuring long-term sustainability of zoo operations. The present study aimed to assess bacterial air contamination level and microclimate conditions in Zagreb Zoo. Measurements were performed in the area for visitors and employees inside four premises, i.e., Monkey House, Tropical House, Rainy Africa, and Bird House, as well as outside the premises in the summer–autumn period. Total number of bacteria in the premises ranged from 4.50 × 10² to 3.70 × 10⁴ CFU/m³, and number of Gram-negative bacteria ranged from 0 to 5.50 × 10² CFU/m³. Total number of bacteria in outdoor air ranged from 50 to 8.50 × 10² CFU/m³, and number of Gram-negative bacteria ranged from 0 to 50 CFU/m³. Total number of bacteria was significantly higher in the Rainy Africa and Bird House as compared to the Monkey House and Tropical House, yielding a significant positive correlation with the number of Gram-negative bacteria in the premises. Total number of bacteria in outdoor air was significantly lower as compared to all investigated premises, except for the Monkey House, yielding a significant positive correlation with the number of Gram-negative bacteria outdoors. Air temperature showed a significant negative correlation with both total number of bacteria and number of Gram-negative bacteria, and airflow rate showed a significant negative correlation with total number of bacteria in the premises. Air temperature showed a significant positive correlation and relative humidity significant negative correlation with total number of bacteria outdoors. Study results can serve in the development of air quality standards in zoos, contributing to finding effective strategies to mitigate health risk from bioaerosols, with implications for occupational and public health, and overall zoo sustainability.

Air quality management in zoological gardens plays a crucial role in their sustainable development. However, air quality in these settings remains understudied. In addition, previous research has largely focused on airborne microbial contamination merely in animal enclosures. This exploratory study provides preliminary insights into airborne fungal contamination alongside microclimate conditions in the visitor and worker areas of animal premises in the Zagreb Zoo. The study was performed in the Monkey House, Tropical House, Rainy Africa, and Bird House, as well as outdoors in fall. Fungi were identified based on macroscopic and microscopic examinations. Total culturable fungal concentration in indoor air ranged between 50 and 4.25 × 10³ CFU/m³, and in outdoor air between 1.00 × 10² and 1.50 × 10³ CFU/m³. Molds of eight genera and yeasts were isolated from the air. Both indoors and outdoors, the predominant genera were Cladosporium and Penicillium, and also genus Aspergillus indoors. Cladosporium spp. and Penicillium spp. concentrations, as well as total fungal concentration in the air, were on average, highest in Rainy Africa and Bird House, while the highest average Aspergillus spp. concentration was found in the Tropical House. Levels of Cladosporium spp., Penicillium spp., and Aspergillus spp. concentrations were associated with microclimate conditions. Study results suggest that the airborne fungal contamination may depend on the animals housed in the premises, and the design and management of the premises. Although total fungal concentration determined may not necessarily pose a health risk for exposed people, the qualitative composition of fungi signifies the importance of implementing good practices in zoo premises, including optimal microclimate conditions and effective ventilation. The results obtained also indicate the need for air quality monitoring, which concurs with zoo sustainability goals.

Mačke su među najbrojnijim kućnim ljubimcima Zapadnog svijeta. Kao kućni ljubimci ovise o vlasniku i često su izložene stresnim podražajima zbog neznanja i neinformiranosti o njihovim vrsno/pasminsko specifičnim potrebama. U ovom radu sažeti su najčešći i najistaknutiji čimbenici i problemi dobrobiti mačaka – kućnih ljubimaca. Glavni uzroci narušene dobrobiti najčešće su neprikladni smještaj i hranidba, uz nemogućnost izražavanja vrsno karakterističnog ponašanja. Takvi uvjeti mogu rezultirati bolestima, poremećajima u ponašanju ili pak neželjenim ponašanjima. Zato bi se vlasnici prije nabavke mačke trebali informirati o njezinim potrebama kako bi joj osigurali dobro fizičko i mentalno zdravlje.
