Can a human with COVID-19 infect a cat?
Humans with COVID-19 cannot infect cats.
COVID-19 does not infect cats. This is because cats and humans have different DNA and RNA; the COVID-19 virus cannot replicate and spread on a cat's RNA, therefore it cannot be transmitted to cats.
Furthermore, the success of China's COVID-19 prevention and control demonstrates that controlling human movement can curb the spread of COVID-19. In this process, the movement of cats did not lead to the failure of COVID-19 prevention and control, which also indirectly proves that cats cannot be infected with COVID-19. 
Cats generally do not get infected with the novel coronavirus because they possess a special protein called the ACE2 receptor, which cannot bind to the S protein of the novel coronavirus. Therefore, cats cannot be infected with the virus. While cats cannot transmit the novel coronavirus, people infected with the novel coronavirus may contract it after close contact with cats.
The virus can be transmitted through droplets and aerosols and may adhere to cat fur. Contact with a cat infected with the novel coronavirus may lead to infection. Therefore, residents should take daily precautions, disinfect frequently, wash hands often, avoid going out unless absolutely necessary, and keep their cats indoors to prevent them from contracting the virus and becoming infected.
