The possibility that humans can infect their pet cats and dogs with the SARS-CoV-2 virus was established during the Covid-19 pandemic. 

In 2020, Canadian researchers suggested that more pets could have contracted Covid-19 than initially though, with numerous reports of the virus in domestic cats. One study found that a cat caught the Delta variant from its owner, Health24 previously reported.

There is also a risk, albeit very small, that animals can pass the virus to people, but there hasn't been any documented evidence of this – until now.
