It’s mass hiss-teria.

Cat owners in China have shared photos in social media of their felines sporting makeshift masks to ward off the deadly coronavirus.

The World Health Organization has said there is no evidence to indicate that the virus – which has killed more than 1,300 people and infected well over 50,000 – can affect pets, the UK’s Sun reported.

But China’s National Health Commission disagrees.

“If pets go out and have contact with an infected person, they have the chance to get infected,” said spokesman and epidemiologist Li Lanjuan.

“By then, pets need to be isolated. In addition to people, we should be careful with other mammals especially pets,” he added.

As a result, sales of pet masks are surging in the country – with one Beijing-based online retailer saying he was selling 10 times the number of special masks for dogs daily than earlier.
