"Come storm our shelter," said OKC Animal Welfare's Facebook post.
The shelter posted pictures of their dogs and cats available for adoption with space filters. Some of the pets are even wearing antennae made out of aluminum foil.
"We have great animals ready to protect you from the Area 51 aliens," the post said. "Adoption isn't that far out of this world!"
The post has led to many adoptions and over $2,000 in donations for the shelter.
