Emily Miller is a cat person—a proud one at that.

“I like to call myself a modern cat lady,” says Miller, the director of special events at the Humane Rescue Alliance and owner of four cats. “It’s cool to love cats now, whereas it used to be a thing people talked about in a negative way.”

She’s got a point: D.C. denizens line up to commune with cats and cappuccinos at the cat cafe (or its kitten pop-up). And remember when the city was briefly obsessed with Ollie, the bobcat who escaped from the National Zoo? (He was later found, don’t worry.) Now, D.C.’s feline enthusiasts can convene at Meow DC, a cat festival benefitting the Humane Rescue Alliance.

On Saturday, Dock 5 behind Union Market will be packed with more than 50 vendors of products and services, many of them cat-specific. There’s clothing and accessories for humans (t-shirts with pithy sayings, cheeky pins, suggestive tote bags) and clothes and items for cats (bow ties, water fountains). There are cat crafts to make and prize giveaways. And Ariana Grande-style cat ears are welcome.

“We’re encouraging people to come dressed in their most fashionable cat attire, whatever that means for you,” says Miller, who dreamed up Meow DC.

And like any good festival, there’s a celebrity presence. Fans can take a photo with Bagel—known as Sunglass Cat on Instagram, where she has more than 500,000 followers—for $15, which will go to the HRA. Following the lead of celebrity festival attendees before her, Sunglass Cat is diligently documenting her D.C. trip on social media. So far, she doesn’t appear to be enjoying the rain.

Outside in the Dock 5 parking lot (pets aren’t allowed inside, so don’t bring your cats from home), the HRA, the Maryland SPCA, and the Animal Welfare League of Arlington will all bring in trucks of adoptable cats (Miller estimates there will be about 40 to 50). Adoptions are available at the festival, and the schedule includes workshops and panels on cat ownership know-how.

“Not everybody is cat savvy—some people like the idea of having a cat but they’ve never had one, so they don’t know what to expect,” Miller says. “If you just want to pick someone’s brain, our adoption staff will be there.”

While she makes no promises about the kind of cats that will be available to take home, she points out that spring is “kitten season,” so there’s a chance some younger felines will be on hand. While the event inside is ticketed, anyone can stop by the parking lot and adopt a new four-legged buddy.

While Miller was inspired by other cat conventions in creating Meow DC (California has CatCon; a festival called Snowcats debuted in Denver last year), she says cats are rarely the star of the show at D.C.’s adoption events. Part of that is logistical: To bring adoptable dogs to an event, all you need is a leash, but cats need a litter box and a crate. “You need people to come to [the cats],” she says.

If Meow DC is successful, can we expect more species-specific celebrations in the future? “Nothing is outside the realm of possibility,” Miller says cryptically. IguanaCon 2020 here we come.

Meow DC takes place at Dock 5 at Union Market on Saturday, 10 a.m.-5 p.m. Tickets $45 at the door.
