However, the infected population is by no means limited to humans. Bats were considered to be the original natural hosts and the most probable source of SARS-CoV-2 infection (Zhou et al., 2020) . In addition, cats, dogs, ferrets and even tigers and lions have been repeatedly reported to be infected with SARS-CoV-2, but no specific case of SARS-CoV-2 Delta variant infection has been reported so far (Hamer et al., 2021; Sailleau et al., 2020) . These stray or companion animals may be a silent intermediate host of SARS-CoV-2 and, therefore, should be screened during the outbreak of epidemic to avoid potential risk of human-animal-human transmission (Halfmann et al., 2020; Wang et al., 2020) . Despite the lack of direct evidence of SARS-CoV-2 transmission from companion animals to humans, the contamination of the environment caused by infected companion animals, especially of closed environments, is of great concern as it is one The letter describes the cat euthanasia event derived from Chinese public news information.
