There is no evidence that pets play a role in spreading the coronavirus in the United States, health authorities said, recommending people to keep cats indoors, walk dogs on a leash and avoid crowded places.

NEW YORK, April 22 (Xinhua) -- Two pet cats in the U.S. state of New York have been infected with the novel coronavirus, becoming the first pets in the United States to test positive for the virus, federal agencies said on Wednesday.

The two cats, which live in separate areas of New York state, have shown mild symptoms and are expected to make a full recovery, according to a statement released by the U.S. Department of Agriculture's National Veterinary Services Laboratories and the U.S. Centers for Disease Control and Prevention (CDC).

In the household of the first cat, no individual has tested positive for COVID-19, and experts believe the cat may have contracted the virus from an infected person outside its home, or from mildly ill or asymptomatic household members.

The second cat's owner had tested positive for COVID-19 before the cat showed signs of respiratory illness, according to the statement.

There is no evidence that pets play a role in spreading the coronavirus in the United States, said the statement. "Therefore, there is no justification in taking measures against companion animals that may compromise their welfare."

As public health experts and officials are still learning about the virus, the CDC recommends people to keep cats indoors, walk dogs on a leash and avoid crowded places like a dog park.

For those who are sick with COVID-19, experts suggest they should restrict contact with their pets and other animals.
