    Two small scale serological investigations have been conducted in the domestic cat populations till now, one in China and another in France [4, 5]. The serological survey conducted in Wuhan, China, reported that 11 out of the total 102 cats tested had SARS-CoV-2 neutralizing antibodies [4]. In the serological survey conducted in France, a total of 9 cats that are living in close contact with their owners were tested. Even though the owners were tested positive for COVID-19, none of the cats were infected that was evident from the negative RT-PCR and serological test results [5]. Since it is very difficult to obtain a general conclusion from these serological surveys, further investigations are required.
