D.C.’s first cat cafe hasn’t even opened yet, but it’s already inspiring spinoffs.

Rock & Roll Hotel, the bar and concert venue on the 1300 block of H Street NE, will be hosting a pop-up cat cafe on Thursday, Dec. 18, from 5 p.m. to 8 p.m. The Washington Humane Society will bring cats available for adoption to a room on the second floor of the establishment.

Steve Lambert, a partner at Rock & Roll Hotel, says he and the other partners got the idea for the event after he heard news of plans for a permanent cat cafe opening in D.C. He says he expects around 60 people to attend.

“That put a little bug in our ear,” Lambert says. “Maybe we can do a one-off event and see how it goes.”

There will be happy-hour prices at the bar for the event. (Which means it’ll start an hour earlier than the usual happy hour there.) That includes $3 PBR tallboys, $4 rails, half-priced wings, and $1 off everything else. Fifteen percent of all bar proceeds will be donated to the Washington Humane Society.

Lambert says the cats will be in cages for the event, and there are no concerns of safety or that someone allergic to cats may haphazardly enter the bar.

“If everyone survives coming to Rock & Roll Hotel with the amount of weirdos that come through here anyway, I think they will be okay with cats in cages,” Lambert says.

Oh, and unlike the actual planned cat cafe, the event at Rock & Roll Hotel will not have a cover charge to play with the cats.
