In the immediacy of the COVID-19 pandemic, we might have forgotten about potential emerging zoonotic disease threats such as companion animals. This paper conducted a thorough review of the literature concerning companion animals-related SAR-CoV-2 cases. Although previously the WHO and CDC asserted that companion animals were unlikely to contract SAR-CoV-2, but more cats and dogs have since tested positive in Hong Kong, Belgium and the U.S. Cats in Belgium presented with clinical symptoms and ~15% of stray and house cats in Wuhan, China have been found to be seropositive. This certainly raises questions about species susceptibility, viral shedding, and asymptomatic reservoirs. The authors suggested researchers start collecting data using in-place animal gatekeepers by providing a simple surveillance form to observe and detect symptoms, as well as investigate animal species density or veterinary reports that could signal disease association with COVID-19 patients.
