(Bloomberg) -- Of all the shortages created by the coronavirus pandemic -- the toilet paper and the hand sanitizer and the bottled water -- the oddest of them all has to be dogs. Oh, and cats too.

That’s right, in the New York city area, the epicenter of the disease, there is suddenly a run on pets. At least of the adopted or fostered kind. Muddy Paws Rescue and Best Friends Animal Society are reporting shelters they work with are either all out of or almost out of cats and dogs after a surge in applications of as much as 10-fold in the past two weeks.

Ordered to shelter in place at home, and both a little bored and a lot anxious, New Yorkers apparently see the four-legged friends as way to calm frayed nerves. “For the moment we definitely don’t have any dogs left to match,” said Anna Lai, the marketing director at Muddy Paws. “Which is a great problem to have.”

It also helps explain why shares of Chewy Inc. are soaring right now even as the stock market overall crashes. It’s up 13% this year, as customers hunker down and order online. The spike in volume has pushed delivery times to between seven and 10 days for most customers, according to the company’s website.

“Chewy’s in-home delivery model mitigates the public health concern of consumers shopping at brick-and-mortar retailers,” RBC Capital Markets said in a report. Another plus: Pet food is mostly recession-proof.

Other pet-centered companies are outperforming, too. PetMed Express Inc. an animal pharmaceutical company is up some 13%, while Freshpet Inc. shares are little changed.

The run on pets seems to extend beyond New York, at least in disease hotspots. The American Society for the Prevention of Cruelty to Animals said its Los Angeles office saw a 70% increase in animals going into foster care. And Best Friends said many of the shelters it partners with across the U.S. report the same phenomenon.

“We’re seeing people show up in droves to foster,” said Julie Castle, chief executive officer of Best Friends. “We have seen the American public come together like we have never seen before and we’ve lived through a lot of tough times like Hurricane Katrina and the 2008 financial crisis.”
