由于户外活动，家畜的寄生虫感染风险可能会增加，通常会导致主人、其他家畜和野生动物之间的传播事件。此外，在家畜中，户外活动尚未被量化为纬度或寄生虫传播途径方面的风险因素。猫是测试户外动物寄生虫感染风险的理想模型，因为已经有许多研究分析了这一物种的这种风险因素;在只在室内的猫和那些有户外活动的猫之间，猫的所有权有一个有用的二分法。因此，我们使用荟萃分析来确定户外活动是否是家养宠物猫寄生虫感染的重要风险因素，包括19种不同的病原体，包括许多与人类，家畜和野生动物健康相关的病原体，如弓形虫和猫弓蛔虫。有户外活动的猫感染寄生虫的可能性是只在室内活动的猫的2.77倍。此外，绝对纬度趋于显著性，绝对纬度每增加一度，感染可能性增加4%。因此，限制户外活动可以降低猫的寄生虫感染风险，并降低人畜共患寄生虫传播的风险，对同域野生动物的溢出以及对猫科动物健康的负面影响。
Parasitic infection risks in domestic animals may increase as a result of outdoor activities, often leading to transmission events to and from owners, other domestic animals and wildlife. Furthermore, outdoor access has not been quantified in domestic animals as a risk factor with respect to latitude or parasite transmission pathway. Cats are an ideal model to test parasitic infection risk in outdoor animals because there have been many studies analysing this risk factor in this species; and there is a useful dichotomy in cat ownership between indoor-only cats and those with outdoor access. Thus, we used meta-analysis to determine whether outdoor access is a significant risk factor for parasitic infection in domestic pet cats across 19 different pathogens including many relevant to human, domestic animal and wildlife health, such as Toxoplasma gondii and Toxocara cati. Cats with outdoor access were 2.77 times more likely to be infected with parasites than indoor-only cats. Furthermore, absolute latitude trended towards significance such that each degree increase in absolute latitude increased infection likelihood by 4%. Thus, restricting outdoor access can reduce the risk of parasitic infection in cats and reduce the risk of zoonotic parasite transmission, spillover to sympatric wildlife and negative impacts on feline health.
