Shelters in Moore and Oklahoma City are taking in lost pets and trying to reconnect them with their owners.
Anyone looking for a pet can go to www.okclostpets.com to post a notice describing the animal and where it was last seen.
Those who have found animals among the wreckage also can post notices on the website to notify the owners.
As of Tuesday afternoon, the site had nearly 100 postings of found pets and 140 posts seeking pets.
Christy Counts, president of the Central Oklahoma Humane Society, said the website is the first place people should look for lost pets.
Animals have been taken to several metro shelters, and a temporary shelter has been set up at the Cleveland County Fair Grounds, 615 E Robinson St., in Norman.
Many of the animals originally were dropped off at the Moore Home Depot, 650 SW 19. Volunteers set up a makeshift shelter inside the store just hours after the storm hit Monday afternoon.
The store sits south of one of the most devastated areas of Moore, but sustained little damage.
Oklahoma City veterinarian Vance Campbell was treating animals at the store Tuesday afternoon and said they had as many as 50 pets at one time.
Campbell said they had reunited a number of pets with their owners Tuesday, but plenty of pets still were looking for their friends.
Jeremy Willoughby was at Home Depot looking for his dog, Penny. He left his house shortly before the storm to pick up his son from Plaza Towers Elementary School.
After riding out the storm at the Warren Theatre, Willoughby said he hasn't been able to get back to his house.
“I don't know if it's is there right now. I don't know,” he said.
Counts said she expects to have about 100 animals by Wednesday at the Oklahoma City Animal Shelter, 2811 SE 29. All the animals pictures will be placed on the website.
Gayla Sesher, supervisor of the Moore Animal Shelter, said they have treated more than 50 animals since Monday afternoon.
