One animal shelter is inviting people to storm its Oklahoma City location and pick up some adorable tin-foil-hat-wearing critters to "protect you from Area 51 aliens."
"Adoption is not that far out of this world! " the Oklahoma City Animal Shelter wrote on its Facebook page Friday.
The event description humorously calls for people to raid and the US military site known as Area 51
About 1.7 million users have marked that they are going to the event.
